This study examines whether repetitive paired-pulse TMS induces offline changes in corticospinal excitability, finding that stimulation targeting inhibition reduces excitability for up to 40 minutes.

This study examines theta-gamma phase-amplitude coupling during sensorimotor adaptation tasks and finds task-dependent spatial patterns of modulation.

This study shows that repeated suprathreshold paired-pulse TMS at short inter-stimulus intervals increases corticospinal excitability over time, suggesting potential for modulating motor system activity.

This study investigates how mild traumatic brain injury affects neurophysiological functions in the dorsolateral prefrontal cortex using TMS-EEG, finding reduced inhibition and plasticity with some contradictory spectral responses.

This study uses pharmaco-EEG to show diazepam alters alpha oscillation shape features in specific brain regions, supporting the neurophysiological relevance of waveform shape in non-invasive human recordings.

This study examines bilateral neuromuscular adaptation after unilateral resistance exercise in older adults, finding reduced MVC in both legs but no change in MU potentials in the non-exercised limb.

This study shows that theta-gamma tACS over M1 improves motor skill acquisition in both young and older adults, with stronger effects in young adults and lasting benefits up to 60 minutes post-training.

This study examines the effects of iTMS on visuomotor training using TMS-EEG, finding no change in MEP amplitude but suggesting altered cortical reactivity and a potential priming effect.

This study investigates how auditory and somatosensory inputs contribute to TMS-evoked potentials (TEPs) in different cortical regions and finds that later TEPs reflect sensory input while earlier peaks reflect cortical stimulation.

The paper examines how age affects the shape of alpha and beta oscillations during reaction time tasks using EEG data from young and older adults.

The paper investigates how PMd stimulation affects M1 neuroplasticity in young and older adults, finding that PMd disrupts specific I-wave facilitation in both groups.

This study investigates how cerebellar transcranial direct current stimulation (tDCSCB) affects neuroplasticity in intracortical motor circuits by comparing responses to different iTMS protocols.

This study investigates using TMS-EEG to assess cerebellar-brain inhibition (CBI) responses, finding that specific coils alter EEG potentials related to motor inhibition.

This study examines how different intervals of repetitive paired-pulse transcranial magnetic stimulation (iTMS) affect intracortical excitability and I-wave circuits using TMS-EEG.

This study assesses the feasibility of using cerebellar TMS-EEG to explore cerebellar-cerebral network dynamics, finding that artefacts and sensory contamination complicate interpretation of early latency signals.

This study investigates how different interstimulus intervals in iTMS affect motor cortex plasticity and finds that facilitation varies with ISI and stimulation direction, with baseline SICF predicting iTMS response.
