Although Transcranial Magnetic Stimulation (TMS) Has Been Introduced Only Recently, It Is Safe And Provides A Painless, Inexpensive Noninvasive Method For The Evaluation Of Brain Function. Determining Central Motor Conduction Time (CMCT) Permits Assessment Of The Corticospinal Pathways. Mapping The Central Representation Of Muscles Provides A Method For Investigating The Cortical Reorganization That Follows Training, Amputation And Injury To The Central Nervous System. Such Studies Of Human Plasticity May Have Important Implications For Neurorehabilitation. TMS Also Provides A Method Whereby Cortical Excitability Can Be Noninvasively Evaluated, Which Is Likely To Have Important Implications In The Study Of Epilepsy, Movement Disorders And Related Conditions. TMS Is Useful In Tracking The Flow Of Information From One Brain Region To Another And In Investigations Of Cognition And Functional Localization, Thereby Complementing Information Obtained Using Functional Imaging Techniques, Which Have Superior Spatial But Inferior Temporal Resolution. Finally, TMS Is Currently Being Investigated As A Method For Establishing Cerebral Dominance And As A Therapeutic Tool In The Treatment Of Depression. Investigations For Treatment Of Other Neurologic And Psychiatric Conditions Are Likely To Be Undertaken.
