Momentary reward induce changes in excitability of primary motor cortex

Research highlights ► By using transcranial magnetic stimulation (TMS), we tested the primary motor cortex (M1) function during the processing of the momentary reward signals. ► We found the increased intracortical inhibition and decreased afferent inhibition of M1 in response to the momentary rewar...

Zusammenfassung:	Research highlights ► By using transcranial magnetic stimulation (TMS), we tested the primary motor cortex (M1) function during the processing of the momentary reward signals. ► We found the increased intracortical inhibition and decreased afferent inhibition of M1 in response to the momentary reward signals. ► Our findings suggest the existence of the reward-related function of human M1.
