[Brain activity induced by changes in acoustic stimuli].
The averaged variants of the EPs to deviant stimuli had more obvious components N100, N250 and P300 as compared with the EPs to standard stimuli. The data obtained show occurrence of a negative shift during presentation of a rare stimulus within the sequence of standard ones. This negativity seems to reflect the processes of comparison of acting excitations with the traces of previous stimuli.
