Noise-induced temporary threshold shift in macaques disrupts electrophysiological temporal processing despite recovery of cochlear sensitivity and preserved ribbon synapse counts

This study shows that temporary threshold shift in macaques causes lasting impairments in temporal auditory processing despite normal hearing thresholds and preserved hair cells.

Spectrotemporal signatures of driving and modulatory circuits across cortical and subcortical networks

The paper identifies spectrotemporal signatures of driving and modulatory circuits in the macaque brain using multiunit activity and oscillatory phase coherence across sensory and motor conditions.

Temporal integration in the subcortical auditory system and behavioral evidence of its dysfunction after "temporary" noise-induced hearing loss

This study examines temporal integration in the subcortical auditory system of nonhuman primates before and after noise exposure, finding disrupted psychometric integration and increased dynamic range post-exposure.

Hierarchical transformations in sound envelope encoding differ across cortical layers

The paper analyzes how amplitude-modulation encoding varies across cortical layers and hemispheres in nonhuman primates, finding differences in frequency ranges and laminar gradients between primary and tertiary auditory areas.

Cochlear histopathology in macaques after noise-induced temporary threshold shifts

This study examines cochlear histopathology in macaques after noise-induced temporary threshold shifts, finding no significant loss of hair cells or synapses but chronic ribbon enlargement.

Persistent impairment of spatial hearing and neural binaural interaction after temporary noise-induced hearing loss

The paper shows that temporary noise-induced hearing loss in nonhuman primates leads to long-lasting spatial hearing deficits and reduced binaural neural processing without synapse loss.

Is there a ubiquitous spectrolaminar motif of local field potential power across primate neocortex?

This paper evaluates the universality and reliability of a spectrolaminar motif in primate neocortex, finding it not universal and methods unreliable.

Hierarchical differences in the encoding of sound and choice in the subcortical auditory system

This study measures auditory detection performance and single-unit activity in subcortical structures of macaques, revealing hierarchical differences in how sound and choice are encoded between the cochlear nucleus and inferior colliculus.

Psychometric and subcortical neurometric measures of temporal discrimination in rhesus macaques

The paper compares psychometric and neurometric measures of temporal discrimination in rhesus macaques, showing subcortical thresholds are higher and more variable than behavioral thresholds.
