Acute cortical stroke alters neural activity in the subthalamic nucleus, which correlates with motor disability in rats

This study examines how acute cortical stroke affects neural activity in the subthalamic nucleus of rats and links these changes to motor disability.

Exploring the Suitability of Piecewise-Linear Dynamical System Models for Cognitive Neural Dynamics

This study evaluates piecewise-linear dynamical system models for cognitive neural dynamics, finding they outperform linear models in artificial data but not in monkey perceptual decision data.

Neural Mechanisms of tDCS: Insights from an In-Vivo Rodent Model with Realistic Electric Field Strengths

This study uses an in-vivo rat model to investigate how weak electric fields from tDCS affect cortical neurons, showing field strength-dependent changes in membrane polarization and spiking activity.

Trigeminal nerve direct current stimulation causes sustained increase in neural activity in the rat hippocampus

This study shows that trigeminal nerve direct current stimulation increases hippocampal spike rates and alters spike-field coherence, mediated through the locus coeruleus-noradrenergic pathway.

Understanding Neuromodulation Pathways in tDCS: Brain Stem Recordings in Rat During Trigeminal Nerve Direct Current Stimulation

This study investigates how direct current stimulation of the trigeminal nerve modulates neural activity in rat brainstem nuclei and shows that blocking the nerve reverses this effect.
