Multivariate Concavity Amplitude Index (MCAI) for characterizing Heschl's gyrus shape

NeuroImage, 2023
Heschl's gyrus (HG), which includes primary auditory cortex, is highly variable in its shape (i.e. gyrification patterns), between hemispheres and across individuals.

TASH: Toolbox for the Automated Segmentation of Heschl's gyrus. [PDF]

Sci Rep, 2020
Abstract Auditory cortex volume and shape differences have been observed in the context of phonetic learning, musicianship and dyslexia. Heschl’s gyrus, which includes primary auditory cortex, displays large anatomical variability across individuals and hemispheres.

Heschl’s gyrus and the temporal pole: The cortical lateralization of language

NeuroImage
The left lateralization of language has been attributed to hemispheric specialization for processing rapidly changing information. While interhemispheric differences in auditory cortex organization support this view, the macrostructure of the entire ...

Human primary auditory cortex follows the shape of Heschl's gyrus. [PDF]

J Neurosci, 2011
The primary auditory cortex (PAC) is central to human auditory abilities, yet its location in the brain remains unclear. We measured the two largest tonotopic subfields of PAC (hA1 and hR) using high-resolution functional MRI at 7 T relative to the underlying anatomy of Heschl's gyrus (HG) in 10 individual human subjects.

Structural Analysis of Heschl’s Gyrus in Schizophrenia Patients with Auditory Hallucinations [PDF]

Neuropsychobiology, 2009
<i>Background/Aims:</i> Heschl’s gyrus (HG) is functionally involved in the genesis of auditory verbal hallucinations (AVH). This dysfunction seems to be structurally facilitated. The aim of the study was to analyze macrostructural features of HG in a group of patients reporting AVH who demonstrated white matter diffusion tensor imaging ...

Reduced volume of Heschl's gyrus in tinnitus

NeuroImage, 2009
The neural basis of tinnitus is unknown. Recent neuroimaging studies point towards involvement of several cortical and subcortical regions. Here we demonstrate that tinnitus may be associated with structural changes in the auditory cortex. Using individual morphological segmentation, the medial partition of Heschl's gyrus (mHG) was studied in ...

Dichotic Pitch activates Pitch Processing Centre in Heschl's Gyrus

NeuroImage, 2009
Although several neuroimaging studies have reported pitch-evoked activations at the lateral end of Heschl's gyrus, it is still under debate whether these findings truly represent activity in relation to the perception of pitch or merely stimulus-related features of pitch-evoking sounds.

Asymmetries of the planum temporale and Heschl's gyrus: relationship to language lateralization [PDF]

Brain, 2006
Morphological asymmetries favouring the left hemisphere in the planum temporale (PT) and Heschl's gyrus (HG) have both been presumed to relate to the typical left-hemisphere dominance for language functions. However, a direct link between structure and function has not been clearly established. The present study investigates this issue by measuring the

Direct Electrical Stimulation of Heschl's Gyrus for Tinnitus Treatment

The Laryngoscope, 2008
AbstractObjectives/Hypothesis: The purpose of the study was to determine the effect of electrical stimulation of the auditory cortex in patients with tinnitus.Study Design: Nonrandomized clinical trial.Methods: Two patients with debilitating tinnitus refractory to conventional therapies were treated.

Transsylvian and trans-Heschl's gyrus approach for a left posterior insular lesion and functional analyses of the left Heschl's gyrus: illustrative case. [PDF]

J Neurosurg Case Lessons, 2022
BACKGROUND A common surgical approach for dominant insular lesions is to make a surgical corridor in asymptomatic cortices based on functional mapping. However, the surgical approach is difficult for posterior insular lesions in a dominant hemisphere because the posterior parts of the perisylvian cortices ...
