The excitability of the human motor cortex during development implicit and declarative knowledge a task was examined. During serial reaction time test, subjects developed test sequence, which reflected by diminishing response times. Motor cortical mapping with transcranial magnetic stimulation revealed that output maps to muscles involved in became progressively larger until explicit achieved, after they returned their baseline topography. These results illustrate rapid functional plasticity outputs associated learning transfer from an state.
