Aim: Major depressive disorder (MDD) is characterized by altered activity in various higher-order regions like the anterior cingulate and prefrontal cortex. While some findings also show changes in lower-order sensory regions like the occipital cortex in MDD, the latter's exact neural and temporal, e.g.

Objective: There are fewer reports on the ictal electroencephalogram(EEG) of convulsions in infants and children with mild gastroenteritis (BCWG). Our study retrospectively analyzed the ictal EEG characteristics of convulsive episodes of BCWG.
Methods: The seizure-phase EEGs of children diagnosed with BCWG from September 2016 to January 2022 were searched and analyzed, and a total of thirteen seizure-phase EEGs of eight cases were analyzed retrospectively.
Predicting regional tau accumulation with machine learning-based tau-PET and advanced radiomics.

Introduction: Alzheimer's disease is partially characterized by the progressive accumulation of aggregated tau-containing neurofibrillary tangles. Although the association between accumulated tau, neurodegeneration, and cognitive decline is critical for disease understanding and clinical trial design, we still lack robust tools to predict individualized trajectories of tau accumulation. Our objective was to assess whether brain imaging biomarkers of flortaucipir-positron emission tomography (PET), in combination with clinical and genomic measures, could predict future pathological tau accumulation.

The complicated processes of carrying out a hand reach are still far from fully understood. In order to further the understanding of the kinematics of hand movement, the simultaneous representation of speed, distance, and direction in the brain is explored.We utilized electroencephalography (EEG) signals and hand position recorded during a four-direction center-out reaching task with either quick or slow speed, near and far distance.

Background: Childhood cerebral type of Adrenoleukodystrophy (CC-ALD) is fatal without hematopoietic stem cell transplantation (HSCT). We consider whether EEGs showing focal paroxysmal delta waves can be a candidate of early detector of the apparent ALD and HSCT therapy.
Methods: Twenty-two male children with ALD (5-16 years; 10.
