Brain microstructure mediates the relationship between Alzheimer's proteinopathies and memory [PDF]

Alzheimers Dement
Abstract INTRODUCTION We examined how amyloid beta (Aβ) and tau accumulation affected gray matter (GM) microstructural integrity and how such alterations impacted memory. METHODS We tested voxel‐wise mediation models to examine the relationships between (1) positron emission tomography‐derived Aβ and tau accumulation and GM microstructural integrity ...

Coding of repetitive transients by auditory cortex on Heschl's gyrus.

J Neurophysiol, 2009
The capacity of auditory cortex on Heschl's gyrus (HG) to encode repetitive transients was studied in human patients undergoing surgical evaluation for medically intractable epilepsy. Multicontact depth electrodes were chronically implanted in gray matter of HG. Bilaterally presented stimuli were click trains varying in rate from 4 to 200 Hz. Averaged

Volume of Left Heschl's Gyrus and Linguistic Pitch Learning [PDF]

Cerebral Cortex, 2007
Research on the contributions of the human nervous system to language processing and learning has generally been focused on the association regions of the brain without considering the possible contribution of primary and adjacent sensory areas. We report a study examining the relationship between the anatomy of Heschl's Gyrus (HG), which includes ...

Processing of an Audiobook in the Human Brain Is Shaped by Cultural Family Background

Brain Sciences, 2022
Perception of the same narrative can vary between individuals depending on a listener’s previous experiences. We studied whether and how cultural family background may shape the processing of an audiobook in the human brain.

Neuromagnetic Evidence for a Pitch Processing Center in Heschl's Gyrus [PDF]

Cerebral Cortex, 2003
There have been several attempts to use the neuromagnetic response to the onset of a tonal sound (N100m) to study pitch processing in auditory cortex. Unfortunately, a large proportion of the N100m is simply a response to the onset of sound energy, independent of whether the sound produces a pitch.

A method for placing Heschl gyrus depth electrodes. [PDF]

Journal of neurosurgery, 2010
A wide range of devices is used to obtain intracranial electrocorticography recordings in patients with medically refractory epilepsy, including subdural strip and grid electrodes and depth electrodes. Penetrating depth electrodes are required to access some brain regions, and 1 target site that presents a particular technical challenge is the first ...

A Discriminative Characterization of Heschl’s Gyrus Morphology using Spectral Graph Features [PDF]

2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021
Abstract Heschl’s Gyrus (HG), which hosts the primary auditory cortex, exhibits large variability not only in size but also in its gyrification patterns, within (i.e., between hemispheres) and between individuals. Conventional structural measures such as volume, surface area and thickness do not capture the full morphological complexity

Cerebral Perfusion Patterns of Anxiety State in Patients With Pulmonary Nodules: A Study of Cerebral Blood Flow Based on Arterial Spin Labeling

Frontiers in Neuroscience, 2022
Background and PurposeThe proportion of patients with somatic diseases associated with anxiety is increasing each year, and pulmonary nodules have become a non-negligible cause of anxiety, the mechanism of which is unclear.

Enhanced peripheral visual processing in congenitally deaf humans is supported by multiple brain regions, including primary auditory cortex

Frontiers in Human Neuroscience, 2014
Brain reorganization associated with altered sensory experience clarifies the critical role of neuroplasticity in development. An example is enhanced peripheral visual processing associated with congenital deafness, but the neural systems supporting this
