Co-release of GABA and ACh from medial olivocochlear neurons fine tunes cochlear efferent inhibition
Castagnola T, Castagna V, Kitcher S, Torres Cadenas L, Di Guilmi M, Gomez Casati M, et al.
bioRxiv
. 2024 Aug;
PMID: 39185230
During development, inner hair cells (IHCs) in the mammalian cochlea are unresponsive to acoustic stimuli but instead exhibit spontaneous activity. During this same period, neurons originating from the medial olivocochlear...

Bachman J, Kitcher S, Vattino L, Beaulac H, Chaves M, Rivera I, et al.
bioRxiv
. 2024 Apr;
PMID: 38586043
Cochlear outer hair cells (OHCs) are electromotile and are implicated in mechanisms of amplification of responses to sound that enhance sound sensitivity and frequency tuning. They send information to the...

Carpaneto Freixas A, Moglie M, Castagnola T, Salatino L, Domene S, Marcovich I, et al.
J Neurosci
. 2020 Nov;
41(1):47-60.
PMID: 33203744
The lateral line (LL) is a sensory system that allows fish and amphibians to detect water currents. LL responsiveness is modulated by efferent neurons that aid in distinguishing between external...

J Neurosci
. 2020 May;
40(25):4842-4857.
PMID: 32430293
The organ of Corti, the auditory mammalian sensory epithelium, contains two types of mechanotransducer cells, inner hair cells (IHCs) and outer hair cells (OHCs). IHCs are involved in conveying acoustic...

Di Guilmi M, Boero L, Castagna V, Rodriguez-Contreras A, Wedemeyer C, Gomez-Casati M, et al.
J Neurosci
. 2019 Jun;
39(36):7037-7048.
PMID: 31217330
The auditory system in many mammals is immature at birth but precisely organized in adults. Spontaneous activity in the inner ear plays a critical role in guiding this maturation process....

Kearney G, Zorrilla de San Martin J, Vattino L, Elgoyhen A, Wedemeyer C, Katz E
J Neurosci
. 2019 Feb;
39(18):3360-3375.
PMID: 30755493
In the mature mammalian cochlea, inner hair cells (IHCs) are mainly innervated by afferent fibers that convey sound information to the CNS. During postnatal development, however, medial olivocochlear (MOC) efferent...

Wedemeyer C, Vattino L, Moglie M, Ballestero J, Maison S, Di Guilmi M, et al.
J Neurosci
. 2018 Mar;
38(16):3939-3954.
PMID: 29572431
Gain control of the auditory system operates at multiple levels. Cholinergic medial olivocochlear (MOC) fibers originate in the brainstem and make synaptic contacts at the base of the outer hair...

Open Biol
. 2013 Dec;
3(11):130163.
PMID: 24350389
Spontaneous electrical activity generated by developing sensory cells and neurons is crucial for the maturation of neural circuits. The full maturation of mammalian auditory inner hair cells (IHCs) depends on...

J Neurosci
. 2013 Sep;
33(39):15477-87.
PMID: 24068816
The synapse between olivocochlear (OC) neurons and cochlear mechanosensory hair cells is cholinergic, fast, and inhibitory. The inhibitory sign of this cholinergic synapse is accounted for by the activation of...

J Assoc Res Otolaryngol
. 2009 May;
10(3):397-406.
PMID: 19452222
Efferent inhibition of cochlear hair cells is mediated by alpha9alpha10 nicotinic cholinergic receptors (nAChRs) functionally coupled to calcium-activated, small conductance (SK2) potassium channels. Before the onset of hearing, efferent fibers...
