Corticofugal modulation of audition
(Elsevier, 2020)
The mammalian brain is connected to the ear through corticofugal pathways. These neural circuits link non-auditory regions of the cerebral cortex like frontal and visual areas with the auditory cortex or the inferior ...
Selective Attention to Visual Stimuli Reduces Cochlear Sensitivity in Chinchillas
(SOC NEUROSCIENCE, 2007-04)
It is generally accepted that during periods of attention to specific stimuli there are changes in the neural activity of central auditory
structures; however, it is controversial whether attention can modulate auditory ...
The Olivocochlear Reflex Strength and Cochlear Sensitivity are Independently Modulated by Auditory Cortex Microstimulation
(Springer, 2015)
In mammals, efferent projections to the cochlear receptor are constituted by olivocochlear (OC) fibers that originate in the superior olivary complex. Medial and lateral OC neurons make synapses with outer hair cells and ...
Effects of Electrical Stimulation of Olivocochlear Fibers in Cochlear Potentials in the Chinchilla
(SPRINGER, 2011-06)
The mammalian cochlea has two types of sensory cells; inner hair cells, which receive auditory-nerve afferent innervation, and outer hair cells, innervated by efferent axons of the medial olivocochlear (MOC) system. The ...
Cochlear hair cells: The sound-sensing machines
(Elsevier, 2015-08-31)
The sensory epithelium of the mammalian inner ear contains two types of mechanosensory cells:inner (IHC) and outer hair cells (OHC). They both transduce mechanical force generated by soundwaves into electrical signals. In ...
Electrical properties and functional expression of ionic channels in cochlear inner hair cells of mice lacking the α10 nicotinic cholinergic receptor subunit
(Springer, 2009-06)
Cochlear inner hair cells (IHCs) release neurotransmitter onto afferent auditory nerve fibers in response to sound stimulation. During early development, synaptic transmission is triggered by spontaneous Ca2+ spikes which ...
The olivocochlear reflex strength in awake chinchillas is relevant for behavioural performance during visual selective attention with auditory distractors
(Nature, 2020)
The auditory efferent system comprises descending projections from the cerebral cortex to subcortical nuclei, reaching the cochlear receptor through olivocochlear fibres. One of the functions attributed to this corticofugal ...
Stronger efferent suppression of cochlear neural potentials by contralateral acoustic stimulation in awake than in anesthetized chinchilla
(Frontiers Research Foundation, 2015)
© 2015 Aedo, Tapia, Pavez, Elgueda, Delano and Robles.There are two types of sensory cells in the mammalian cochlea, inner hair cells, which make synaptic contact with auditory-nerve afferent fibers, and outer hair cells ...
