Cortical Activity During an Attack of Ménière's Disease—A Case Report

open access: yesFrontiers in Neurology, 2021
Background: Ménière's disease (MD) is a chronic peripheral vestibular disorder with recurrent episodes of vertigo accompanied by fluctuating hearing loss, tinnitus and aural fullness in the affected ear. There are several unanswered fundamental questions

Differential activity in Heschl's gyrus between deaf and hearing individuals is due to auditory deprivation rather than language modality [PDF]

open access: yes, 2015
Sensory cortices undergo crossmodal reorganisation as a consequence of sensory deprivation. Congenital deafness in humans represents a particular case with respect to other types of sensory deprivation, because cortical reorganisation is not only a ...

Study of Brain Structure and Function in Chronic Mountain Sickness Based on fMRI

open access: yesFrontiers in Neurology, 2022
Objective: Headache and memory impairment are the primary clinical symptoms of chronic mountain sickness (CMS). In this study, we used voxel-based morphometry (VBM) and the amplitude of the low-frequency fluctuation method (ALFF) based on blood oxygen ...

Representation of Instantaneous and Short-term Loudness in the Human Cortex

open access: yesFrontiers in Neuroscience, 2016
Acoustic signals pass through numerous transforms in the auditory system before perceptual attributes such as loudness and pitch are derived. However, relatively little is known as to exactly when these transformations happen, and where, cortically or ...

Cell density and cortical thickness in Heschl's gyrus in schizophrenia, major depression and bipolar disorder

open access: yes, 2004
There is evidence that the superior temporal gyrus and Heschl's gyrus within it are implicated in schizophrenia. We investigated neuronal and glial cell density and cortical thickness within Heschl's gyrus, using the optical disector to estimate cell ...

Cerebral Micro-Structural Changes in COVID-19 Patients – An MRI-based 3-month Follow-up Study

open access: yesEClinicalMedicine, 2020
Background: Increasing evidence supported the possible neuro-invasion potential of SARS-CoV-2. However, no studies were conducted to explore the existence of the micro-structural changes in the central nervous system after infection. We aimed to identify

Sparse Spectro-Temporal Receptive Fields Based on Multi-Unit and High-Gamma Responses in Human Auditory Cortex. [PDF]

open access: yesPLoS ONE, 2015
Spectro-Temporal Receptive Fields (STRFs) were estimated from both multi-unit sorted clusters and high-gamma power responses in human auditory cortex. Intracranial electrophysiological recordings were used to measure responses to a random chord sequence ...

A Case of Cortical Deafness due to Bilateral Heschl Gyrus Infarct [PDF]

open access: yesCase Reports in Medicine, 2017
We report the case of a 58-year-old male who presented with an episode of seizure and abrupt onset hearing loss. Neuroimaging revealed acute infarcts in bilateral Heschl gyri. Objective tests of peripheral auditory function were essentially normal and a diagnosis of cortical deafness was made.

Local Heschl's Gyrus-based coordinate system for intersubject comparison of M50 auditory response modeled by single equivalent current dipole

open access: yes, 2010
Allocating electromagnetic auditory responses to active regions in the human auditory cortex can be difficult because of high interindividual variability of the relevant structures. Location and orientation of the primary auditory cortex (Heschl's Gyrus)

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

open access: yesEpileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.
