Speech Biomarkers From Smartphone Calls Track Progression in REM Sleep Behavior Disorder and Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective This 24‐month longitudinal study involving isolated rapid eye movement sleep behavior disorder (iRBD), early‐stage Parkinson's disease (PD), and matched healthy control subjects aimed to assess whether acoustic speech features from real‐world smartphone calls provide passive progressive biomarkers in synucleinopathies.

3D Hydrogel Cell Cultures and Their Biomedical Applications

open access: yesAdvanced NanoBiomed Research, EarlyView.
The review highlights the advantages of hydrogel‐based 3D cell cultures over traditional 2D models. These hydrogels closely mimic natural cellular environments, improving research in tissue engineering, drug discovery, cancer studies, and neuroscience.

Auditory cortical activity drives feedback-dependent vocal control in marmosets

open access: yesNature Communications, 2018
During vocalization, mammals change their vocal production to compensate for altered auditory feedback. Here, Eliades and Tsunada show that neural activity in the marmoset’s auditory cortex mediates this effect, and that stimulation of the auditory ...

Change detection in children with autism: an auditory event-related fMRI study [PDF]

open access: yes, 2006
Autism involves impairments in communication and social interaction, as well as high levels of repetitive, stereotypic and ritualistic behaviours, and extreme resistance to change. This latter dimension, whilst required for a diagnosis, has received less

Plasticity in the frequency representation of primary auditory cortex following discrimination training in adult owl monkeys

open access: yesJournal of Neuroscience, 1993
Previous studies have shown that the tonotopic organization of primary auditory cortex is altered subsequent to restricted cochlear lesions (Robertson and Irvine, 1989) and that the topographic reorganization of the primary somatosensory cortex is ...

Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Stereological Assessments of Neuronal Pathology in Auditory Cortex in Schizophrenia

open access: yesFrontiers in Neuroanatomy, 2018
It has long been known that auditory processing is disrupted in schizophrenia. More recently, postmortem studies have provided direct evidence that morphological alterations to neurons in auditory cortex are implicated in the pathophysiology of this ...

Altered white matter structure in auditory tracts following early monocular enucleation [PDF]

open access: yes, 2019
Purpose: Similar to early blindness, monocular enucleation (the removal of one eye) early in life results in crossmodal behavioral and morphological adaptations.

A synaptic and circuit basis for corollary discharge in the auditory cortex

open access: yesNature, 2014
Sensory regions of the brain integrate environmental cues with copies of motor-related signals important for imminent and ongoing movements. In mammals, signals propagating from the motor cortex to the auditory cortex are thought to have a critical role ...
