Activation of Heschl’s Gyrus during Auditory Hallucinations [PDF]

Neuron, 1999
Apart from being a common feature of mental illness, auditory hallucinations provide an intriguing model for the study of internally generated sensory perceptions that are attributed to external sources. Until now, the knowledge about the cortical network that supports such hallucinations has been restricted by methodological limitations.

Relating structure to function: Heschl's gyrus and acoustic processing. [PDF]

J Neurosci, 2009
The way in which normal variations in human neuroanatomy relate to brain function remains largely uninvestigated. This study addresses the question by relating anatomical measurements of Heschl's gyrus (HG), the structure containing human primary auditory cortex, to how this region processes temporal and spectral acoustic information.

Differences in Intrinsic Brain Abnormalities Between Patients With Left- and Right-Sided Long-Term Hearing Impairment

Frontiers in Neuroscience, 2019
Unilateral hearing impairment is characterized by asymmetric hearing input, which causes bilateral unbalanced auditory afferents and tinnitus of varying degrees. Long-term hearing imbalance can cause functional reorganization in the brain.

Representations of pitch and slow modulation in auditory cortex [PDF]

, 2013
Iterated ripple noise (IRN) is a type of pitch-evoking stimulus that is commonly used in neuroimaging studies of pitch processing. When contrasted with a spectrally matched Gaussian noise, it is known to produce a consistent response in a region of ...

Smaller Hippocampal Volume and Degraded Peripheral Hearing Among Japanese Community Dwellers

Frontiers in Aging Neuroscience, 2018
A growing body of literature has demonstrated that dementia and hearing loss are interrelated. Recent interest in dementia research has expanded to brain imaging analyses with auditory function.

Altered Intrinsic Functional Connectivity in Language-Related Brain Regions in Association with Verbal Memory Performance in Euthymic Bipolar Patients

Brain Sciences, 2013
Potential abnormalities in the structure and function of the temporal lobes have been studied much less in bipolar disorder than in schizophrenia. This may not be justified because language-related symptoms, such as pressured speech and flight of ideas ...

Language prediction mechanisms in human auditory cortex

Nature Communications, 2020
The human brain fluently parses continuous speech during perception and production. Using direct brain recordings coupled with stimulation, the authors identify separable substrates underlying two distinct predictive mechanisms of “when” in Heschl’s ...

Critical-Network Lesion-Symptom Mapping. [PDF]

Hum Brain Mapp
We introduce Critical‐Network Lesion‐Symptom Mapping (CN‐LSM), an atlas‐based approach that uses ensemble modeling and out‐of‐sample prediction to identify brain networks supporting behavior in stroke patients. CN‐LSM outperforms standard multivariate methods in ground‐truth recovery while delivering interpretable, low‐dimensional results with fewer ...

Sexual Dimorphism Within Brain Regions Controlling Speech Production

Frontiers in Neuroscience, 2019
Neural processing of speech production has been traditionally attributed to the left hemisphere. However, it remains unclear if there are structural bases for speech functional lateralization and if these may be partially explained by sexual dimorphism ...

Functional Brain Connectivity in Mild Cognitive Impairment With Sleep Disorders: A Study Based on Resting-State Functional Magnetic Resonance Imaging

Frontiers in Aging Neuroscience, 2022
PurposeTo investigate the effect of sleep disorder (SD) on the changes of brain network dysfunction in mild cognitive impairment (MCI), we compared network connectivity patterns among MCI, SD, and comorbid MCI and sleep disorders (MCI-SD) patients using ...
