Examining the Relationship between Aerobic Fitness and Cortical Excitability

, 2017
Because of its ability to enhance cortical excitability, aerobic exercise is receiving interest as a primer for learning and rehabilitation. Previous studies show that physical activity level influences the brain s response to exercise.

Reduced intracortical inhibition and enhanced intracortical facilitation in patients with functional tremor

BMJ Neurology Open
Background The pathophysiological mechanism underlying functional tremor (FT) has not been elucidated. Transcranial magnetic stimulation (TMS) is a non-invasive tool to explore cortical excitability in various neurological and neuropsychiatric disorders.

Linking cortical network synchrony and excitability [PDF]

Communicative & Integrative Biology, 2016
Theoretical approaches based on dynamical systems theory can provide useful frameworks to guide experiments and analysis techniques when investigating cortical network activity. The notion of phase transitions between qualitatively different kinds of network dynamics has been such a framework inspiring novel approaches to neurophysiological data ...

MethyAnno: An Interpretable Automated Annotation Method Leveraging Multi‐Scale Information and Metric Learning Framework for scDNAm Data

Advanced Science, EarlyView.
MethyAnno enables robust and interpretable annotation of single‐cell DNA methylation data by integrating multi‐scale epigenetic information, bidirectional cross‐attention, and prototype‐based metric learning. The framework resolves rare and novel cell types across datasets while revealing cell‐type‐specific epigenetic signatures associated with disease

Resting state cortical electroencephalographic rhythms in covert hepatic encephalopathy and Alzheimer's disease [PDF]

, 2013
Patients suffering from prodromal (i.e., amnestic mild cognitive impairment, aMCI) and overt Alzheimer's disease (AD) show abnormal cortical sources of resting state electroencephalographic (EEG) rhythms.

A Multi‐Scale Computational Framework for Evaluating Wireless Neuromodulation Feasibility via Magnetoelectric Nanoparticles

Advanced Science, EarlyView.
A multiscale computational framework links single‐nanoparticle magnetoelectric behavior to tissue‐level electric field distributions, integrating experimental data from nanoparticle characterization and in vitro stimulation setups. Applied to a cortical slice configuration, the framework predicts optimal MENP concentrations and stimulation parameters ...

Decoding the Neural Circuit Underlying Context‐Cue Association in Retrieval of Morphine Reward Memory

Advanced Science, EarlyView.
Contextual cues recruit the glutamatergic vCA1–dmPFC pathway to retrieve morphine reward memory by reshaping cell‐type‐specific prefrontal microcircuit activity. Distinct regulation of PV+ and SST+ interneurons defines this hippocampal–prefrontal mechanism.
