Аннотация:Eyeblink signals and evoked potentials were recorded and averaged in humans during the tachistoscopic presentation of gratings at various spatial frequencies and levels of luminance. It was confirmed that at high spatial frequencies and low levels of luminance the latency of evoked potentials increased and their amplitude decreased. At the same time there was a longer inhibition of the eyeblink, which was more precisely timed on the stimulus. This points to the existence of a central system that regulates the eyeblink in accordance with the attention involved in visual information processing.
