Impact of the COVID-19 pandemic on college students' mental health and lifestyle factors.

This study examines how mental health and health behaviors evolved among college students nationwide before and during the onset of the COVID-19 pandemic. Data collected from college students across various campuses in Fall 2019 ( = 33,372) and Fall 2020 ( = 34,168) as part of the Healthy Minds Study. : The online survey was delivered Qualtrics.

A universal automated tool for reliable detection of seizures in rodent models of acquired and genetic epilepsy.

Objective: Prolonged electroencephalographic (EEG) monitoring in chronic epilepsy rodent models has become an important tool in preclinical drug development of new therapies, in particular those for antiepileptogenesis, disease modification, and treating drug-resistant epilepsy. We have developed an easy-to-use, reliable, computational tool for automated detection of electrographic seizures from prolonged EEG recordings in rodent models of epilepsy.

Methods: We applied a novel method based on advanced time-frequency analysis that detects EEG episodes with excessive activity in certain frequency bands.

Quantum theory of mass potentials.

Probabilistic formalism of quantum mechanics is used to quantitatively link the global scale mass potential with the underlying electrical activity of excitable cells. Previous approaches implemented methods of classical physics to reconstruct the mass potential in terms of explicit physical models of participating cells and the volume conductor. However, the multiplicity of cellular processes with extremely intricate mixtures of deterministic and random factors prevents the creation of consistent biophysical parameter sets.

Cortical arousal in children and adolescents with functional neurological symptoms during the auditory oddball task.

Objective: Stress, pain, injury, and psychological trauma all induce arousal-mediated changes in brain network organization. The associated, high level of arousal may disrupt motor-sensory processing and result in aberrant patterns of motor function, including functional neurological symptoms. We used the auditory oddball paradigm to assess cortical arousal in children and adolescents with functional neurological symptom disorder.
