Repeated paired associative stimulation combining peripheral nerve stimulation and transcranial magnetic stimulation (TMS) of the primary motor cortex (M1) can produce human motor plasticity. However, previous studies used paired artificial stimuli, so that it is not known whether repetitive natural M1 activity associated with TMS can induce plasticity or not. To test this hypothesis, we developed a movement-related cortical stimulation ... إقراء المزيد
