Abstract:
Objective: To investigate the distribution features of somatosensory cortical evoked potential map with augmented blocking of the sensation transmission along meridians.Method: The EEG-4400 electro-encephalogram (EEG) and ND-1 brain electrical activity mapping were adopted on 11 volunteers with remarkable sensation transmission along meridians, showing that the sensation can transmit to head and face after stimulating the points below the knee joints. Also, special observation was made on accurate location of somatosensory cortical evoked potential map in 10 people without sensation transmission.Result: Observation on 11 volunteers with remarkable transmission along the Three Foot-yang Meridians showed that they presented with concurrent high potential reactions in somatosensory cortical lower limbs and face without blocking the augmented sensation transmission along the meridians; however, when mechanical pressure was exerted to block the sensation transmission,only one reaction in the lower limbs occurred in the somatosensory cortical evoked map and the other one in the face disappeared. Conclusion: Peripheral tissue evoking is the decisive factor for transmission along the meridians.
