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

This study examines age-related differences in alpha power modulation during visual working memory with distractors, finding that younger adults, but not older adults, show alpha power changes in anticipation of distractors.

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 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 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 examines age differences in aperiodic neural activity using resting EEG, finding that older adults have flatter 1/f-like slopes and lower broadband power, which affects alpha oscillation measures.

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.

This study investigates how alpha power relates to inhibiting anticipated distractors in verbal working memory, finding increased alpha power before distractors but no effect of distractor strength.

This study examines how alpha oscillations change with working memory load in young and older adults, finding similar load-dependent patterns but differences in alpha power during retention.
