From sound to meaning in the auditory cortex: A neuronal representation and classification analysis [PDF]

open access: yesarXiv, 2023
The neural mechanisms underlying the comprehension of meaningful sounds are yet to be fully understood. While previous research has shown that the auditory cortex can classify auditory stimuli into distinct semantic categories, the specific contributions of the primary (A1) and the secondary auditory cortex (A2) to this process are not well understood.

Binary Spiking in Auditory Cortex [PDF]

open access: yesThe Journal of Neuroscience, 2003
Neurons are often assumed to operate in a highly unreliable manner: a neuron can signal the same stimulus with a variable number of action potentials. However, much of the experimental evidence supporting this view was obtained in the visual cortex. We have, therefore, assessed trial-to-trial variability in the auditory cortex of the rat.

Efficient Coding Approach Towards Non-Linear Spectro-Temporal Receptive Fields [PDF]

open access: yesarXiv, 2021
Linear Non-Linear(LN) models are widely used to characterize the receptive fields of early-stage auditory processing. We apply the principle of efficient coding to the LN model of Spectro-Temporal Receptive Fields(STRFs) of the neurons in primary auditory cortex.

A Brain System for Auditory Working Memory [PDF]

open access: yes, 2016
The brain basis for auditory working memory, the process of actively maintaining sounds in memory over short periods of time, is controversial. Using functional magnetic resonance imaging in human participants, we demonstrate that the maintenance of ...

Representations of Pitch and Timbre Variation in Human Auditory Cortex

open access: yesJournal of Neuroscience, 2017
Pitch and timbre are two primary dimensions of auditory perception, but how they are represented in the human brain remains a matter of contention. Some animal studies of auditory cortical processing have suggested modular processing, with different ...

Auditory attention activates peripheral visual cortex. [PDF]

open access: yesPLoS ONE, 2009
BackgroundRecent neuroimaging studies have revealed that putatively unimodal regions of visual cortex can be activated during auditory tasks in sighted as well as in blind subjects.

Speaker-normalized sound representations in the human auditory cortex [PDF]

open access: yes, 2019
The acoustic dimensions that distinguish speech sounds (like the vowel differences in “boot” and “boat”) also differentiate speakers’ voices. Therefore, listeners must normalize across speakers without losing linguistic information.

The Auditory Cortex in Schizophrenia [PDF]

open access: yesBiological Psychiatry, 2007
Sweet et al have recently shown that the somal volume of pyramidal cells is reduced in layer 3 of the auditory cortex in schizophrenic patients (Sweet et al 2004; Sweet et al 2003). In this issue of Biological Psychiatry, they report new data showing that the density of axon terminals is also significantly decreased in the same layer (Sweet et al 2006).

Auditory Cortex Characteristics in Schizophrenia: Associations With Auditory Hallucinations

open access: yesSchizophrenia bulletin, 2017
Background: Neuroimaging studies have demonstrated associations between smaller auditory cortex volume and auditory hallucinations (AH) in schizophrenia. Reduced cortical volume can result from a reduction of either cortical thickness or cortical surface

Effects of acute high‐altitude exposure on working memory: A functional near‐infrared spectroscopy study

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
The current study adopted an experimental paradigm of digital span to evaluate acute high‐altitude exposure impairment on working memory. The subjects showed obvious physiological adaptation mechanism at acute altitude. The results of hemodynamic response confirmed the important role of left DLPFC in the process of working memory, revealed abnormal ...
