Coding of amplitude modulation in primary auditory cortex

P Yin, JS Johnson, KN O'Connor… - Journal of …, 2011 - journals.physiology.org
Conflicting results have led to different views about how temporal modulation is encoded in
primary auditory cortex (A1). Some studies find a substantial population of neurons that …

Ability of primary auditory cortical neurons to detect amplitude modulation with rate and temporal codes: neurometric analysis

JS Johnson, P Yin, KN O'Connor… - Journal of …, 2012 - journals.physiology.org
Amplitude modulation (AM) is a common feature of natural sounds, and its detection is
biologically important. Even though most sounds are not fully modulated, the majority of …

Dynamic amplitude coding in the auditory cortex of awake rhesus macaques

BJ Malone, BH Scott… - Journal of …, 2007 - journals.physiology.org
In many animals, the information most important for processing communication sounds,
including speech, consists of temporal envelope cues below∼ 20 Hz. Physiological studies …

Amplitude modulation encoding in the auditory cortex: comparisons between the primary and middle lateral belt regions

JS Johnson, M Niwa, KN O'Connor… - Journal of …, 2020 - journals.physiology.org
In macaques, the middle lateral auditory cortex (ML) is a belt region adjacent to the primary
auditory cortex (A1) and believed to be at a hierarchically higher level. Although ML single …

Hierarchical differences in population coding within auditory cortex

JD Downer, M Niwa, ML Sutter - Journal of …, 2017 - journals.physiology.org
Most models of auditory cortical (AC) population coding have focused on primary auditory
cortex (A1). Thus our understanding of how neural coding for sounds progresses along the …

Selective effects of arousal on population coding of natural sounds in auditory cortex

CR Heller, ZP Schwartz, D Saderi, SV David - bioRxiv, 2020 - biorxiv.org

Rate, not selectivity, determines neuronal population coding accuracy in auditory cortex

W Sun, DL Barbour - PLoS biology, 2017 - journals.plos.org
The notion that neurons with higher selectivity carry more information about external sensory
inputs is widely accepted in neuroscience. High-selectivity neurons respond to a narrow …
