Modulation of human primary motor cortex plasticity during proactive and retroactive interference between motor practice and paired associative stimulation
This study compared the primary motor cortex (M1) plasticity responses when motor practice was performed before or after paired associative stimulation (PAS25) and explored whether these responses were accompanied by changes in intracortical inhibition.
Unveiling the plastic mechanisms of the primary visual cortex (V1) is crucial for understanding how visual processing can change and adapt, ultimately informing interventions to promote functional recovery following visual system damage. Paired associative stimulation (PAS) protocols can induce associative plasticity w...

It was found that both unilateral and bilateral stimulation improved bimanual coordination compared to sham, with no difference between montages, and brain dynamics were associated with sensorimotor performance in an exploratory analysis, thereby potentially linking stimulation-sensitive CAPs to motor performance.

Abstract Motor skill performance is associated with early changes in corticospinal excitability (CSE), yet the influence of rest periods surrounding motor activity on these neurophysiological responses remains unclear. This study examined how matched pre‐ and post‐activity rest intervals influence CSE following novel f...

Theta-gamma (TG) transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation technique that can improve performance of simple motor tasks when applied over primary motor cortex (M1). However, the effects of TG tACS on performance of more complex motor tasks remain to be investigated. Forty h...

The inter-trial interval (ITI) of transcranial magnetic stimulation (TMS) can modulate motor-evoked potential (MEP) amplitude and may thus confound assessments of corticospinal excitability. We tested whether this effect depends on the ITI duration per se or the associated temporal predictability and whether intracorti...

Brain oscillations shape cortical excitability in a phase-dependent manner. Cortical excitability reflects the net output of intracortical circuits, including inhibitory and facilitatory pathways. However, whether the phase of ongoing brain rhythms differentially modulates inhibitory and facilitatory responses remains...
