Abstract:
In this paper the event-related potential (ERP) of selective attention to the left and right visual field is investigated with 3D tomography technique. The results show that compared with the scalp surface ERP data, the current source intensity derived from tomography can better reflect the enhanced effect of P1 and N1, especially N1. Moreover, C1 component can be observed in the results, which cannot be identified in the scalp data.
