Macrophages Are Dispensable for Postnatal Pruning of the Cochlear Ribbon Synapses

open access: yesFrontiers in Cellular Neuroscience, 2021
Ribbon synapses of cochlear hair cells undergo pruning and maturation before the hearing onset. In the central nervous system (CNS), synaptic pruning was mediated by microglia, the brain-resident macrophages, via activation of the complement system ...

Protection of Cochlear Ribbon Synapses and Prevention of Hidden Hearing Loss

open access: yesNeural Plasticity, 2020
In the auditory system, ribbon synapses are vesicle-associated structures located between inner hair cells (IHCs) and spiral ganglion neurons that are implicated in the modulation of trafficking and fusion of synaptic vesicles at the presynaptic ...

Sensory Processing at Ribbon Synapses in the Retina and the Cochlea [PDF]

open access: yesPhysiological Reviews, 2020
In recent years, sensory neuroscientists have made major efforts to dissect the structure and function of ribbon synapses which process sensory information in the eye and ear. This review aims to summarize our current understanding of two key aspects of ribbon synapses: 1) their mechanisms of exocytosis and endocytosis and 2) their molecular anatomy ...

Distinct synaptic transfer functions in same-type photoreceptors

open access: yeseLife, 2021
Many sensory systems use ribbon-type synapses to transmit their signals to downstream circuits. The properties of this synaptic transfer fundamentally dictate which aspects in the original stimulus will be accentuated or suppressed, thereby partially ...

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

open access: yes, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

Transmitter release from cochlear hair cells is phase locked to cyclic stimuli of different intensities and frequencies [PDF]

open access: yes, 2012
The auditory system processes time and intensity through separate brainstem pathways to derive spatial location as well as other salient features of sound.

Autophagy-Mediated Synaptic Refinement and Auditory Neural Pruning Contribute to Ribbon Synaptic Maturity in the Developing Cochlea

open access: yesFrontiers in Molecular Neuroscience, 2022
In rodents, massive initial synapses are formed in the auditory peripheral nervous system at the early postnatal stage, and one of the major phenomena is that the number of afferent synapses in the cochlea is significantly reduced in the duration of ...

Synaptic mitochondria regulate hair-cell synapse size and function

open access: yeseLife, 2019
Sensory hair cells in the ear utilize specialized ribbon synapses. These synapses are defined by electron-dense presynaptic structures called ribbons, composed primarily of the structural protein Ribeye.

Endocytosis and Vesicle Recycling at a Ribbon Synapse [PDF]

open access: yesThe Journal of Neuroscience, 2003
At ribbon synapses, where exocytosis is regulated by graded depolarization, vesicles can fuse very rapidly with the plasma membrane (complete discharge of the releasable pool in ∼200 msec). Vesicles are also retrieved very rapidly (time constant of ∼1 sec), leading us to wonder whether their retrieval uses an unusual mechanism.

A Gata3–Mafb transcriptional network directs post-synaptic differentiation in synapses specialized for hearing

open access: yeseLife, 2013
Information flow through neural circuits is determined by the nature of the synapses linking the subtypes of neurons. How neurons acquire features distinct to each synapse remains unknown.
