This concept is underscored by the fact that fan cells of the entorhinal cortex are indispensable for the formation of episodic-like memories in rodents. [9] Single-unit recording of neurons in humans playing video games find path cells in the EC, the activity of which indicates whether a person is taking a clockwise or counterclockwise path ...
To transmit the sensation of sound to the brain, where it can be processed into the perception of hearing, hair cells of the cochlea must convert their mechanical stimulation into the electrical signaling patterns of the nervous system. Hair cells are modified neurons, able to generate action potentials which can be transmitted to other nerve ...
Deiters' cells (phalangeal cells) are a type of neuroglial cell found in the organ of Corti and organised in one row of inner phalangeal cells and three rows of outer phalangeal cells. They are the supporting cells of the hair cell area within the cochlea. They are named after the German pathologist Otto Deiters (1834–1863) who described them.
The olivocochlear system is a component of the auditory system involved with the descending control of the cochlea.Its nerve fibres, the olivocochlear bundle (OCB), form part of the vestibulocochlear nerve (VIIIth cranial nerve, also known as the auditory-vestibular nerve), and project from the superior olivary complex in the brainstem to the cochlea.
The organ of Corti is located in this duct on the basilar membrane, and transforms mechanical waves to electric signals in neurons. The other two sections are known as the scala tympani and the scala vestibuli. These are located within the bony labyrinth, which is filled with fluid called perilymph, similar in composition to cerebrospinal fluid.
Neurons whose cell bodies lie in the spiral ganglion are strung along the bony core of the cochlea, and send fibers into the central nervous system (CNS). These bipolar neurons are the first neurons in the auditory system to fire an action potential, and supply all of the brain's auditory input.
Deiters' cells, also known as outer phalangeal cells or cells of Deiters (English: / ˈ d aɪ t ər z /), are a cell type found within the inner ear. They contain both microfilaments and microtubules which run from the basilar membrane to the reticular membrane of the inner ear.
Type I neurons make up 90-95% of the neurons and innervate the inner hair cells. They have relatively large diameters, are bipolar, and are myelinated. Each type I axon innervates only a single inner hair cell, but each inner hair cell is innervated by up to 30 such nerve fibers, depending on species and location within the cochlea.
