Optogenetic Stimulation of the Auditory Nerve [PDF]

Journal of Visualized Experiments, 2014
Direct electrical stimulation of spiral ganglion neurons (SGNs) by cochlear implants (CIs) enables open speech comprehension in the majority of implanted deaf subjects(1-) (6). Nonetheless, sound coding with current CIs has poor frequency and intensity resolution due to broad current spread from each electrode contact activating a large number of SGNs ...

An investigation of dendritic delay in octopus cells of the mammalian cochlear nucleus

Frontiers in Computational Neuroscience, 2012
Octopus cells, located in the mammalian auditory brainstem, receive their excitatory synaptic input ex-clusively from auditory nerve fi□bers. They respond with accurately timed spikes but are broadly tunedfor sound frequency.

Regeneration of the auditory nerve - a cell transplantation study [PDF]

, 2011
Since in mammals, the hair cells or the spiral ganglion neurons (SGNs) in the inner ear do not regenerate, damage to these cells is an irreversible process.

Perception of stochastically undersampled sound waveforms: A model of auditory deafferentation

Frontiers in Neuroscience, 2013
Auditory deafferentation, or permanent loss of auditory nerve afferent terminals, occurs after noise overexposure and aging and may accompany many forms of hearing loss. It could cause significant auditory impairment but is undetected by regular clinical

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

Advanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

Intraoperative electrocochleographic characteristics of auditory neuropathy spectrum disorder in cochlear implant subjects [PDF]

, 2017
Auditory neuropathy spectrum disorder (ANSD) is characterized by an apparent discrepancy between measures of cochlear and neural function based on auditory brainstem response (ABR) testing.

Nurr1 Orchestrates Claustrum Development and Functionality

Advanced Science, EarlyView.
Nurr1 (Nr4a2) is the master transcription factor to control claustrum morphogenesis and cell fate decision postmitotically by inhibiting intracellular G‐protein signaling. Nurr1 deficiency alters the transcriptomic profiles of subcortical claustral neurons into neocortical insular neurons, resulting in defected claustrum development, impaired axonal ...

How we see [PDF]

, 2008
The visual world is imaged on the retinas of our eyes. However, "seeing"' is not a result of neural functions within the eyes but rather a result of what the brain does with those images.
