Cortical morphology alterations in non-COVID-19 post-infectious olfactory dysfunction

Scientific Reports
While COVID-19-associated olfactory dysfunction leads to gray matter (GM) structural alterations, it remains unclear whether these structural GM alterations are specific to COVID-19.

Glymphatic dysfunction couples with cortical excitation–inhibition imbalance in epilepsy: Evidence from Rasmussen encephalitis

Epilepsia, EarlyView.
Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.

Revisiting the Neural Basis of Acquired Amusia: Lesion Patterns and Structural Changes Underlying Amusia Recovery

Frontiers in Neuroscience, 2017
Although, acquired amusia is a common deficit following stroke, relatively little is still known about its precise neural basis, let alone to its recovery.

Association between a longer duration of illness, age and lower frontal lobe grey matter volume in schizophrenia [PDF]

, 2008
The frontal lobe has an extended maturation period and may be vulnerable to the long-term effects of schizophrenia. We tested this hypothesis by studying the relationship between duration of illness (DoI), grey matter (GM) and cerebro-spinal fluid (CSF ...

Artificial intelligence in preclinical epilepsy research: Current state, potential, and challenges

Epilepsia Open, EarlyView.
Abstract Preclinical translational epilepsy research uses animal models to better understand the mechanisms underlying epilepsy and its comorbidities, as well as to analyze and develop potential treatments that may mitigate this neurological disorder and its associated conditions. Artificial intelligence (AI) has emerged as a transformative tool across

Temporal trajectory of brain tissue property changes induced by electroconvulsive therapy

NeuroImage, 2021
Background: After more than eight decades of electroconvulsive therapy (ECT) for pharmaco-resistant depression, the mechanisms governing its anti-depressant effects remain poorly understood.

Disrupted Brain Structure and Function in Alzheimer's Disease Patients With Behavioral and Psychological Symptoms

iNew Medicine, EarlyView.
ABSTRACT Behavioral and psychological symptoms of dementia (BPSD) are highly prevalent in Alzheimer's disease (AD), but the underlying mechanisms are unclear. This study aims to elucidate the neuropathological mechanisms underlying BPSD by investigating gray matter volume (GMV) and brain connectivity in AD patients with and without BPSD.

Voxel-based morphometry in hypocretin-deficient narcolepsy. [PDF]

Sleep, 2003
Recent studies suggest that narcolepsy is caused by degeneration of hypocretin (orexin) producing neurons. To find evidence for this hypothesis, we aimed to detect structural changes in the hypothalamus and/or hypocretin projection areas of patients with narcolepsy.We used voxel-based morphometry (VBM), an unbiased MRI morphometric method with a high ...
