    Abstract:
    Auditory evoked potentials (AEPs) were recorded in 10 adult healthy subjects under conditions of simple rhythmical stimulation and during solving selective attention task. Middle- (10-60 ms) and long-latency (up to 400 ms) AEPs were analysed by AEP mapping and by evaluation of their spatio-temporal characteristics. it is suggested that interaction between the parietal, left temporal and left frontal cortical areas exerts efferent influence to brainstem structures over a period of 15-35 ms. Amplitudes of P90 and P250 components were reduced during selective attention task. The late P350 component increases, mainly, in the central and frontal cortical areas.
