MOTOR EVOKED POTENTIALS AND TRANSCUTANEOUS MAGNETO-ELECTRICAL NERVE STIMULATION
Keywords: neurometrics, brain electrical activity mapping, isometric contracting
AbstractThe purpose of this study was to identify the mechanism of cerebral cortex human isometric contraction information processing. By using transcutaneous magneto-electrical nerve stimulation technique, musculi flexor crapi radialis/ulnaris isometric contracts, the nerve digitals palmares/volares communes nerve mediani/ulnaris were stimulated. The results showed that many evoked potential amplitude of gyrus postcentralis and praecentralis, lobules parietals superior and inferior, gyrus temporaries’ superior/medius/inferior are significantly different to each other. Some peak absolute latency and interpeak /interwave latency, either sensory or motor was shorter in the same side hemisphere, while those in the opposing side hemisphere were longer. The above results indicated that the sensory afferent information occurred previously in the same side hemisphere rather than the opposing hemisphere.
