Abstract In an ever changing auditory scene, change detection is ongoing task performed by the brain. Neurons in midbrain and cortex that exhibit stimulus-specific adaptation (SSA) may contribute to this process. Those neurons adapt frequent sounds while retaining their excitability rare sounds. Here, we test whether exhibiting SSA those without are part of same networks inferior colliculus (IC). We recorded responses then marked sites these with a retrograde tracer correlate source...

Binding the attributes of a sensory source is necessary to perceive it as unified entity within its surrounding scene in cocktail party problem auditory perception. It postulated that coherent temporal modulation source's features binds them and enhances their This study seeks evidence for rapid binding among coherently responsive single-neurons ferret cortex. In one experiment, ferrets attended sequence noise bursts while we contrasted responses simultaneous synchronized versus alternating...

Binding the attributes of a sensory source is necessary to perceive it as unified entity, one that can be attended and extracted from its surrounding scene. In auditory perception, this essence cocktail party problem in which listener segregates speaker mixture voices, or musical stream simultaneous others.

Speech recognition in noisy environments can be challenging and requires listeners to accurately segregate a target speaker from irrelevant background noise. Stochastic figure-ground (SFG) tasks which temporally coherent inharmonic pure-tones must identified have been used probe the non-linguistic auditory stream segregation processes important for speech-in-noise processing. However, little is known about relationship between performance on SFG nor individual differences that may modulate...

Pitch is a fundamental attribute in auditory perception involved source identification and segregation, music, speech understanding. percepts are intimately related to harmonic resolvability of sound. When harmonics well-resolved, the induced pitch usually salient precise, several models relying on autocorrelations or spectral templates can account for these percepts. However, when not completely resolved, percept becomes less salient, poorly discriminated, with upper range limited few...

Natural sounds such as vocalizations often have covarying acoustic attributes, resulting in redundancy neural coding. The efficient coding hypothesis proposes that sensory systems are able to detect covariation and adapt reduce redundancy, leading more Recent psychoacoustic studies shown the auditory system can rapidly efficiently encode two dimensions a single dimension, following passive exposure which temporal spectral attributes covaried correlated fashion. However, these observed cost...

Neural implants that electrically stimulate neural tissue such as deep brain stimulators, cochlear (CI), and vagal nerve stimulators are becoming the routine treatment options for various diseases. Optimizing electrical stimulation paradigms requires closed-loop using simultaneous recordings of evoked activity in real time. Stimulus-evoked artifacts at recording site generally orders magnitude larger than signals, which challenge interpretation activity. We developed a generalized artifact...

Abstract Natural sounds such as vocalizations often have co-varying acoustic attributes where one feature can be predicted from another, resulting in redundancy neural coding.
