Abstract

The effect of sensory signals coming from skin and muscle afferents on the sensorimotor cortical networks is entitled as sensory-motor integration (SMI). SMI can be studied electrophysiologically by the motor cortex excitability changes in response to peripheral sensory stimulation. These changes include the periods of short afferent inhibition (SAI), afferent facilitation (AF) and late afferent inhibition (LAI). During the early period of motor skill acquisition, motor cortex excitability increases, and changes occur in the area covered by the responsible zone of the motor cortex. In the late period these give place to the morphological changes such as synaptogenesis. SAI decreases during learning the motor skills, while GAI increases in motor activity. In this review, the role of SMI in the process of motor learning and transcranial magnetic stimulation methods performed for studying SMI will be summarized.
