The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered. The Auditory Nerve conveys the neuronal activity generated by the hair cells to a specialized nucleus of the thalamus. It has no motor function. The Anatomy of the CochleaAnatomy. The spiral shape of the cochlea is necessary for the transduction of different sound frequencies. Function. Sound waves are funneled into the ear and strike the eardrum (tympanic membrane) resulting in vibration.Associated Conditions. Several conditions may affect the cochlea. Tests. The health of the cochlea is assessed by several tests. These messages are then passed to the auditory nerve and carried up to the brain. This was consistent with previous findings that children with cochlear nerve deficiency had higher ECAP thresholds with smaller ECAP amplitudes and smaller slopes of ECAP amplitude growth function compared to children with normal-sized cochlear nerves. The nerve has its origin in the bipolar cells of the spiral ganglion of the cochlea, which is located adjacent to the inner margin of the bony spiral lamina. The autonomic nervous system supplies (innervates) organs, like your eyes. The cochlea is a portion of the inner ear that looks like a snail shell (cochlea is Greek for snail). A cochlear implant tries to replace the function of the inner ear by turning sound into electrical energy. It has a purely somatic motor function. The trigeminal nerve, also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.Its name ("trigeminal" = tri-, or three, and - geminus, or twin: so "three-born, triplet") derives from each of the two nerves (one on each Better results are achieved in tumours with tumours located posterior (group 5) or superior (group 3) to the IAC, compared to tumours with premeatal location (group 1) or intrameatal involvement (group 2). It consists of neurons that have their cell bodies in the cochlea that then project into the cochlear nucleus of the medulla in the brain stem. After the eardrum takes in a sound, the sound gets turned into a vibration that travels to the cochlea. We take this nice of Cochlear Nerve graphic could possibly be the most trending topic with we portion it in google pro or facebook. This article discusses the anatomy of the auditory pathway (see the following images), as well as a few physiologic considerations and clinical applications. It enables detection of potential nerve damage and thus contributes to avoiding postoperative functional deficits. Its submitted by direction in the best field. The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. The spiral ganglion in the cochlea's modiolus is where the cochlear nerve's fibres begin. - The auditory nerve root. These cells translate vibrations into electrical impulses that are carried to the brain by sensory nerves. The oculomotor nerve is the third cranial nerve (CN III). . Cochlea is a term derived from the Greek word kokhlias which means spiral, snail shell. It is the smallest cranial nerve (by number of axons), yet has the longest intracranial course. What Is The Function of the Cochlea? The type of modality is sensory, of the special visceral sensory variety. After exiting the cochlea, the auditory nerve enters the brain stem and bifurcates with one branch synapsing in the posteroventral (PVCN) and dorsal (DCN) cochlear nucleus and the other innervating the anteroventral cochlear nucleus (AVCN). Structure of the cochlea. It communicate sound and equilibrium information from the inner ear to the brain. These then travel from the spiral ganglion to the brain. Cochlea. The smell molecules in the nasal cavity trigger nerve impulses that pass along this nerve to the olfactory bulb, then on to limbic areas. These then travel from the spiral ganglion to the brain. The other portion of the vestibulocochlear nerve is the vestibular nerve, The cochlear nucleus is the first brain structure of the central auditory pathway (Fig. . Olfactory nerve. Cochlear Nerve. cochlear nerve function during acoustic neuroma surgery with transtemporal approach: Warning signs as predictors of postoperative hearing loss Inaugural dissertation . CNAP monitoring proved very useful in confirming the location of the cochlear nerve in the operative field and preserving cochlear nerve function. Objective: To analyze auditory nerve recovery function (REC), comparing the results after local anesthesia and sedation with those after general anesthesia. The cochlear nerve is the sole input pathway from the cochlea to the central nervous system. The nerve also enables you to move your eyes toward your nose or away from it. vulnerable: cochlear insults such as noise exposure, ototoxic drugs and hypoxia lead to the elevated threshold and broader tuning that is characteristic of sensorineural hearing loss. The cochlea is a bone in the inner part of the ear. The function of the cochlear nerve begins when sound vibrations hit the eardrum (tympanic membrane). The cochlea is absolutely vital to hearing. It then reorganizes itself again as nerve function is restored." What is the function of co Chlea in the internal ear? What function does the trochlear nerve have?The Central Nervous System: It consists of the brain and the spinal cord. It is the central evaluating and commanding unit.The Peripheral Nervous System: It consists of the following subdivisions. A. 2K views The cochlea is absolutely vital to hearing. The inner ear functions as the sensorineural receptor organ of the auditory system, converting an acoustic waveform into an electrochemical stimulus that can be transmitted to the CNS. Resting on the basilar membrane is the organ of corti, which is lined with cilia, or hairs that are designed to pick up on different types of vibrations of different frequencies. High-risk occupations such as miningConcerts/headphones/earbudsUsing leaf blowers/lawn mowers The hair cells located on How well the cochlear nerve relays these signals contributes to the clarity, or intelligibility, of sound processed within the central nervous system. The fibres of the cochlear nerve originate from an aggregation of nerve cell bodies, the spiral ganglion, located in the modiolus of the cochlea. The bony labyrinth comprises two chambers, called scalae. The cochlea makes 2.75mm round in man around a core of bone (called the modiolus) through which the cochlear nerve passes. They then compared the data to a previous study at Mass Eye and Ear that had tracked the average loss of cochlear nerve fibers as a function of age. By hitting the eardrum, those vibrations are converted into electrical signals that the cochlear nerve carries to the brain. It is made up of two other nerves: the cochlear, which carries information about sound, and the vestibular, which does the same with information about balance. The cochlea is a component of osseous labyrinth that contains perilymph and the cochlear duct. Branching off the vestibule of the inner ear, the cochlea consists of a bony labyrinth spiraling around a central bony core. By hitting the eardrum, those vibrations are converted into electrical signals that the cochlear nerve carries to the brain. Nerve Root. The cochlear duct is a component of membranous labyrinth and contains endolymph. The vestibulocochlear nerve consists of two anatomically and functionally distinct parts: the cochlear nerve, which innervates the organ of hearing, and the vestibular nerve, which innervates the organs of equilibrium. The responses of fibres in the cochlear nerve can, to a first approximation, be considered as the rectified output of a bank of linear bandpass filters, which in most cases have limited dynamic ranges. It enables movement in the eyes superior oblique muscle. The other portion of the vestibulocochlear nerve is the vestibular nerve, which carries spatial orie As these nerve fibers vibrate, they turn frequencies into electrical impulses that are passed, via the Auditory Nerve, to the brain where they are interpreted as sound. Recent research has focussed on a mechanism that could explain the origin of a large number of tinnitus cases: the disruption of the connections (known as synapses) between the sensory cells and the auditory nerve, which the cochlea has a base (= screw head) and an apex (=point) two membranes extend from the spiral lamina to the lateral wall of the cochlea, dividing the bony cochlea into 3 compartments: scala vestibuli, scala tympani and scala media (= cochlear duct) the scalae wind around the modiolus ~3 times, defining apical, middle and basal turns. The cochlea looks like a spiral-shaped snail shell deep in your ear. After exiting the cochlea, the auditory nerve enters the brain stem and bifurcates with one branch synapsing in the posteroventral (PVCN) and dorsal (DCN) cochlear nucleus and the other innervating the anteroventral cochlear nucleus (AVCN).
The cochlea, the part of the inner ear where the cochlear part of the nerve originates, detects soundwaves. Cochlear Nerve. The oculomotor nerve is one of 12 sets of cranial nerves. The cochlea is responsible for the phase of auditory transduction that takes place in the inner ear. By hitting the eardrum, those vibrations are converted into electrical signals that the cochlear nerve carries to the brain. This nerve contains two components: the vestibular nerve and the cochlear nerve. The function of the cochlear nerve begins when sound vibrations hit the eardrum (tympanic membrane). It is used to transform the vibrations of the lymph fluids and their associated structures into an electrical signal that can be transmitted along nerves and into the brain. While it is a bone, it is not part of the skeletal system, rather it is necessary for hearing. It is one of the many pieces that make up the auditory system, which enables effective hearing. The function of the vestibulocochlear nerve is purely sensory. By hitting the eardrum, those vibrations are converted into electrical signals that the cochlear nerve carries to the brain. This thalamic nucleus in turn relays this information to the auditory cortex, which is found within the temporal lobes of the brain. The nerve has its origin in the bipolar cells of the spiral ganglion of the cochlea, which is located adjacent to the inner margin of the bony spiral lamina. And it plays an important part in helping you hear: it changes sounds into nerve messages and sends them to your brain. The function of the vestibulocochlear nerve is purely sensory. Sound is picked up by a microphone worn near the ear. The auditory nerve, also known as the vestibulocochlear nerve or the statoacoustic nerve, is responsible for auditory function and balance. The cochlear nerve is responsible for transmitting auditory signals from the inner ear to the cochlear nuclei, within the brainstem, and ultimately to the primary auditory cortex, within the temporal lobe. The pre-vertebral nerve (n. Vestibulocochlearis) is formed by sensitive nerve fibers from the organs of hearing and balance.
Function The function of the vestibulocochlear nerve is purely sensory. Auditory nerve fibers, fibers that travel through the auditory nerve (also known as the cochlear nerve or eighth cranial nerve) carry information from the inner ear, the cochlea, on the same side of the head, to the nerve root in the ventral cochlear nucleus. Alternatively, the ABR can be initiated through an electrically evoked The cochlear nerve (also auditory nerve or acoustic nerve) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. The outcome of facial and cochlear nerve function is different in CPA meningiomas depending on the topographic classification of these tumours. The vestibulocochlear nerve consists of two anatomically and functionally distinct parts: the cochlear nerve, which innervates the organ of hearing, and the vestibular nerve, which innervates the organs of equilibrium. Many of these nerves are part of the autonomic nervous system. cochlear nerve function during acoustic neuroma surgery with transtemporal approach: Warning signs as predictors of postoperative hearing loss Inaugural dissertation . The cochlear nerve, which innervates the organ of hearing, and the vestibular nerve, which innervates the organs of balance, are morphologically and functionally separate sections of the vestibulocochlear nerve. What is the main function of cochlea? Within this bony spiral is a membranous labyrinth. It supplies the special senses of hearing and balance, with integration to thalamic and cerebellar structures causing postural changes. It enables detection of potential nerve damage and thus contributes to avoiding postoperative functional deficits. The receptor cells for these special senses are located in the membranous labyrinth which is embedded in the petrous part of the temporal bone. / ozdamar, Ozcan; Dallos, Peter. Physiology, Cochlear Function - StatPearls - NCBI Bookshelf Research Dive into the research topics of 'Preservation of cochlear nerve function with the aid of brain stem auditory evoked potentials'. Development and implementation of novel and additional approaches may further improve its clinical value. We take this nice of Cochlear Nerve graphic could possibly be the most trending topic with we portion it in google pro or facebook. Hereof, what is the function of the cochlea in the ear? 59, No.
The tonotopic map created by the spiral of the cochlea enables people to interpret a vast amount of different sounds simultaneously through vibrations carried from the perilymph to the endolymph in the cochlear duct. This happens at the organ of Corti. (before splits off and branches) - Talking about the end of an AN axon. Cranial XII: Motor. The function of the cochlear nerve begins when sound vibrations hit the eardrum (tympanic membrane). Cochlea. 1) Dorsal cochlear nucleus (DCN) 2) Anterior ventral cochlear nucleus (AVCN) 3) Posterior ventral cochlear nucleus (PVCN) Input to the CN. The spiral ganglion in the cochlea's modiolus is where the cochlear nerve's fibres begin. The cochlear nerve can be affected with many different disorders and diseases. The cochlea receives sound in the form of vibrations, which cause the stereocilia to move. The human cochlea allows the perception of sounds between 20 Hz and 20 000 Hz (nearly 10 octaves), with a resolution of 1/230 octave (from 3 Hz at 1000 Hz). It communicate sound and equilibrium information from the inner ear to the brain. Its submitted by direction in the best field. It passes through the modiolus and the base of the cochlea. The vestibulocochlear nerve is the eighth paired cranial nerve. We identified it from obedient source. And it plays an important part in helping you hear: it changes sounds into nerve messages and sends them to your brain. Both facial nerve function and hearing acuity were completely preserved after tumor removal, and wave V latency on BAEP returned to normal and was maintained in the normal range for at least 2 years. Function. It has no motor function. It is used to transform the vibrations of the lymph fluids and their associated structures into an electrical signal that can be transmitted along nerves and into the brain. It communicate ssound and equilibrium information from the inner ear to the brain. It was located counter-clockwise (caudally) to the facial nerve at an angle of 50 degrees on average when they were projected on the right side. The vestibular nerve is one of the two branches of the vestibulocochlear nerve (the cochlear nerve being the other). When it comes to innervation, the cochlear nerve carries sensory hearing information after arising from the spiral ganglion. We take this nice of Cochlear Nerve graphic could possibly be the most trending topic with we portion it in google pro or facebook. The cochlear nerve is one branch of the vestibulocochlear nerve (CN VIII) which innervates the cochlear duct 1,4. Here are a number of highest rated Cochlear Nerve pictures on internet. Related pathology The function of the cochlea is to transform the vibrations of the cochlear liquids and associated structures into a neural signal. A cochlear implant is surgically implanted in the inner ear (the cochlea) and activated by a device worn outside the ear called the speech or sound processor. The vestibulocochlear nerve (auditory vestibular nerve), known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain. The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. {file12616}{file12617}{file12626}The eighth cranial nerve (CN VIII) or vestibulocochlear nerve is composed of 2 different sets of fibers: (1) the cochlear nerve and Cochlear implants are designed to mimic the function of a healthy inner ear (or cochlea). Cochlear tinnitus. The cochlea, the part of the inner ear where the cochlear part of the nerve originates, detects soundwaves. The vestibulocochlear nerve is the eighth paired cranial nerve.
The cochlear nerve is primarily responsible for transmitting the electrical impulses generated for hearing and localization of sound. In this article, we will consider the anatomical course, special sensory functions and
Here are a number of highest rated Cochlear Nerve pictures on internet. Air movement against the eardrum initiates action of the ossicles of the ear, which, in turn, causes movement of fluid in the spiral We identified it from obedient source. When it comes to innervation, the cochlear nerve carries sensory hearing information after arising from the spiral ganglion. The vibration from your eardrum sets your ear bones (malleus, incus, stapes) into motion. cochlear nerves bilaterally but a normal size IAC. The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain. The auditory nerve, also known as the vestibulocochlear nerve or the statoacoustic nerve, is responsible for auditory function and balance. 16, 17 However, ABR is an acoustically driven response affected by pre-existing hearing loss, prohibiting its use during translabyrinthine (TL) approaches. The function of the cochlea is to transform the vibrations of the cochlear liquids and associated structures into a neural signal. This nerve appears forked before the vestibular and cochlear nerve bundles join. Recommended Video: Since they provide special sensory functions ( balance and hearing) this nerve would be functionally categorized as special somatic afferent (SSA) instead of the general somatic afferent. Function. * Nerve root: first part of the neuron entering CNS from the peripheral. The trochlear nerve is the fourth paired cranial nerve. 1, 01.1976, p. 143-147. The nerve also enables you to move your eyes toward your nose or away from it. However, other methods of recording cochlear function have proven useful from both a scientific and clinical perspective. How well the cochlear nerve relays these signals contributes to the clarity, or intelligibility, of sound processed within the central nervous system. It is comprised of two parts vestibular fibres and cochlear fibres.Both have a purely sensory function. Nerve Root. What researchers don't know yet, McFadden said, is how long the brain retains this plasticity -- important clinically to determine how quickly treatment, via hearing aids or cochlear implants, must begin -- or whether a return to normal brain activity means a return to normal hearing. It is normally characterized by preserved outer hair cell function and abnormal neural conduction of the auditory pathway . This happens at the organ of Corti. Objective: To analyze auditory nerve recovery function (REC), comparing the results after local anesthesia and sedation with those after general anesthesia. The oculomotor nerve is the third cranial nerve (CN III). The cochlear nerve can be affected with many different disorders and diseases. * Nerve root: first part of the neuron entering CNS from the peripheral. The cochlear nerve connects to the cochlea, which is one of the parts of the inner ear responsible for hearing. It consists of tiny hair cells that line the cochlea. [3][4] The cochlea is a spiral, fluid-filled cavity in the bony auditory labyrinth that contains the Organ of Corti, along its basilar membrane. Then it goes into the internal auditory canal, where it divides into the pre-door and cochlear parts. The processor captures sound signals and sends them to a receiver implanted under the skin behind the ear. The function of the cochlear nerve begins when sound vibrations hit the eardrum (tympanic membrane).
The trochlear nerve is one of 12 sets of cranial nerves. Air movement against the eardrum initiates action of the ossicles of the ear, which, in turn, causes movement of fluid in the spiral When the vestibulocochlear nerve reaches the inner ear, it again splits into the vestibular and cochlear part which supply target tissues of the inner ear. Even individuals with severe or profound nerve deafness may be able to benefit from cochlear implants. Its submitted by direction in the best field. In humans the vestibular nerve transmits sensory information transmitted by vestibular hair cells located in the two otolith organs (the utricle and the saccule) and the three semicircular canals via the vestibular ganglion of Scarpa. Development and implementation of novel and additional approaches may further improve its clinical value. Other articles where cochlear nerve is discussed: human nervous system: Vestibulocochlear nerve (CN VIII or 8): Auditory receptors of the cochlear division are located in the organ of Corti and follow the spiral shape (about 2.5 turns) of the cochlea. As a result, the inner ear receives sounds successfully, but the cochlea has a problem with sending the signals from the ear to the auditory nerve and brain stem . They replace the function of damaged sensory hair cells inside the inner ear to help provide clearer sound than what hearing aids can provide. Auditory nerve fibres have spontaneous rates that vary from 0 to more than 120 spikes per second. The vestibulocochlear nerve helps with a persons hearing and balance. For years, scientists and clinicians believed hair-cell deterioration was the primary cause of hearing loss and that cochlear nerve damage was widespread only after the hair cells were destroyed. The function of the cochlear nerve begins when sound vibrations hit the eardrum (tympanic membrane). Cochlear Nerve. (before splits off and branches) - Talking about the end of an AN axon. The cochlear nerve, which innervates the organ of hearing, and the vestibular nerve, which innervates the organs of balance, are morphologically and functionally separate sections of the vestibulocochlear nerve. The cochlear nerve (also auditory nerve or acoustic nerve) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. Nerve fibers entering the cochlear nuclei are distributed in an organised, tonotopic, manner: those that come from the apex of the cochlea (low frequencies) remain at the surface of the cochlear nuclei, whereas those of the base (high frequencies) penetrate deeper into the nuclei. cochlear nerve function during acoustic neuroma surgery with transtemporal approach: Warning signs as predictors of postoperative hearing loss Inaugural dissertation . In this article, the anatomical course, motor functions and clinical relevance of the nerve will be examined. Figure 2. The effect of RW involvement on speech discrimination bone of the cochlea cochlear otosclerosis (n=133) but without any other focus were removed from the study. Cochlea converts the auditory signals to neural impulses, which are carried by the afferent nerves fibres and auditory nerves to the brain, where it is integrated and we hear the sound. Auditory nerve fibers, fibers that travel through the auditory nerve (also known as the cochlear nerve or eighth cranial nerve) carry information from the inner ear, the cochlea, on the same side of the head, to the nerve root in the ventral cochlear nucleus. When the vestibulocochlear nerve reaches the inner ear, it again splits into the vestibular and cochlear part which supply target tissues of the inner ear. The vestibulocochlear nerve is a sensory nerve that conducts two special senses: hearing (audition) and balance (vestibular). Your vestibulocochlear nerve has sensory functions involving hearing and balance. The cochlear nerve is primarily responsible for transmitting the electrical impulses generated for hearing and localization of sound. 3.2 Palsy of the Trochlear Nerve. Primary cochlear axons enter the lateral portion of the caudal pons, terminating in the dorsal and ventral cochlear nuclei with several tonotopically representative maps of the auditory frequency world. The cochlea looks like a spiral-shaped snail shell deep in your ear. The olfactory nerves are associated with the function of smell. (3) Reaches the endosteal bone of the cochlea scores approached significance (p=0.055). In the late 1970s, sound was recorded in the external ear canal that was found to be generated by the cochlea itself. Input-output functions of cochlear whole-nerve action potentials : Interpretation in terms of one population of neurons. Appointments 866.588.2264 Appointments & Locations Request an Appointment Function Anatomy Conditions and Disorders The cochlear nerve (also auditory or acoustic nerve) is a nerve in the head that carries signals from the cochlea of the inner ear to the brain. Cochlear implants are designed to mimic the function of a healthy inner ear (or cochlea). The cochlear nerve is the sole input pathway from the cochlea to the central nervous system. The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain. They replace the function of damaged sensory hair cells inside the inner ear to help provide clearer sound than what hearing aids can provide. These nerve impulses are carried by the vestibulocochlear nerve from the cochlea to the brain for interpretation. Large variance in the size and shape of the human cochlea. Here are a number of highest rated Cochlear Nerve pictures on internet. The cochlear nerve (also auditory or acoustic nerve) is a nerve in the head that carries signals from the cochlea of the inner ear to the brain. The trochlear nerve is one of 12 sets of cranial nerves. What Is The Function of the Cochlea? On the ventral surface of the brain, the pre-cochlear nerve leaves behind the bridge, laterally from the facial nerve. Many of these nerves are part of the autonomic nervous system. The Utah Electrode Array (Figure 1), has been surgically implanted into the cochlear nerve of felines for periods of over six months. The receiver sends the signals to electrodes implanted in the snail-shaped inner ear (cochlea). The cochlea is capable of exceptional sound analysis, in terms of both frequency and intensity. The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered. Cochlear implants use a sound processor that fits behind the ear. The cochlear nerve can be affected with many different disorders and diseases. The cochlea, the part of the inner ear where the cochlear part of the nerve originates, detects soundwaves. Auditory Nerve Function. Conclusions: Intraoperative monitoring of the cochlear nerve is an integral component of CPA surgery. Function The pinna of your ear collects sound waves and funnels them through your ear canal to your eardrum. . After the eardrum takes in a sound, the sound gets turned into a vibration that travels to the cochlea. This energy can then be used to stimulate the cochlear nerve (the nerve for hearing), sending "sound" signals to the brain. Methods: This was a prospective, cross-sectional and descriptive study in a tertiary referral center hospital. Of the Eleven patients had normal function of the facial nerves (House-Brackmann grade 1/6), confirming that a solitary nerve in the small IAC was the facial nerve. Since they provide special sensory functions ( balance and hearing) this nerve would be functionally categorized as special somatic afferent (SSA) instead of the general somatic afferent. All 12 patients with congenital SNHL had ipsilat-eral abnormalities of the inner ear structures. Other articles where cochlear nerve is discussed: human nervous system: Vestibulocochlear nerve (CN VIII or 8): Auditory receptors of the cochlear division are located in the organ of Corti and follow the spiral shape (about 2.5 turns) of the cochlea. The other branch is the auditory nerve, sometimes called the cochlear nerve. The cochlea is a bone in the inner part of the ear. It passes through the modiolus and the base of the cochlea. 25.3 ).
Prior studies suggested positive effects of nimodipine for preservation of the nerve function in these patients. The cochlear nerve can be affected with many different disorders and diseases. Thirty-five children diagnosed with cochlear nerve aplasia Cranial XII: Motor. Numerous hypotheses have been suggested about the link between tinnitus and inner ear (cochlear) pathology. These initial projections are ipsilateral, meaning that auditory information from the left ear projects into the left medulla. It is made up of two other nerves: the cochlear, which carries information about sound, and the vestibular, which does the same with information about balance. This study aimed to assess the function of the cochlear nerve using electrically evoked compound action potentials (ECAPs) for children with cochlear implants who were diagnosed with cochlear nerve aplasia and to analyze the correlation between preimplantation imaging results and ECAP responses.
