Dissociable Stimulus- and Response-Driven Serial Dependence Effects in Auditory, Visual, and Audiovisual Motion Judgments

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.

Behavioral evidence for visually dominant audiovisual motion integration

The paper investigates audiovisual motion integration, finding visual dominance and attentional modulation in motion perception tasks.

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.

Physiological, Histological, and Cognitive Characterization of a Macaque Model of Presbycusis

This study characterizes age-related hearing loss in rhesus macaques through histological, physiological, and cognitive assessments, finding correlations between auditory deficits and cognitive impairments.

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.

Integration of Audiovisual Motion in Dorsolateral Prefrontal Cortical Neurons

The paper records single neurons in macaque dorsolateral prefrontal cortex during visual, auditory, and audiovisual motion, showing multisensory integration and nonlinear responses.

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.

Multisensory perception reflects individual differences in processing temporal correlations

The paper investigates how individual differences in temporal processing affect multisensory perception by measuring the impact of audiovisual correlation strength.
