Cerebral Cortex Potentials Evoked in Man by Preceived and Not Preceived Acoustic Stimuli (Vyzvannye Potentsialy kory Golovnogo Mozga Chevloveka na Osoznavaeme i Neosoznavaeme Zvukovye Stimuly),
Abstract
With the aid of the computer, average evoked potentials (AEP) to short acoustic subliminal stimuli (3-10 db below the threshold audibility), liminal intensity and supraliminal intensity (10-60 db above the threshold) were recorded from the vertex and the occipatal region of the skull (healthy subjects). The dynamics of the AEP changes have been demonstrated with an increase in sound intensity from subliminal to supraliminal (60 db) values. Time and amplitude parameters of AEP from perceived and not perceived acoustic stimuli are positively distinguishable from each other. A long-latent, low-amplitude, slow positive wave is the most constant, and in many cases the only component of AEP from a not perceived stimulus. (Author)
