Central conduction studies and magnetic stimulation.

Magnetic stimulation of brain and spinal roots provides non-invasive evaluation of the propagation of nerve impulses as well as characteristics of excitability along the motor pathways. Physiology of motor performances and pathophysiology of movement disorders can be approached with this new technique. Moreover, transcranial stimulation (TCS) of non-motor areas of the brain represents a formidable probe for the evaluation of lateralized hemispheric properties connected with higher cortical functions.
