Abstract

Event-related brain potentials were recorded in 16 young adult subjects in response to a short presentation of recognizable and nonrecognizable visual images with an incomplete set of signes. Sequential brain maps and amplitude-temporal ERP parameters in 1000 ms poststimulis epoch were estimated (BMDP 4M and 7M, 1987). The results suggested that the component N450 was specifically related to a perception of nonrecognizable visual images. N70 and N150 reflected voluntary attention during invariant recognition and the late negative waves (600-1000 ms) reflected an <<exhaustive search>> for categorization of new information.
