Abstract
Author(s): STARR, A; LIVINGSTON, RB | Abstract: MOST NEUROPHYSIOLOGICAL EXPERIMENTS deal with phenomena which last for only a brief period of time, usually measured in milliseconds or seconds. Commonplace subjective experience, however, indicates that longer lasting effects may follow prolonged periods of sensory stimulation, Sensations of motion, for example, may last for hours or days following a rough sea voyage (for a vivid description of this effect see ref. 17). The French refer to this as ma1 de debarquement. Analogously persisting aftereffects are observed in the visual system (e.g., the “waterfall effect”) and auditory and somesthetic systems. We presume that neurophysiological events must underlie these illusions. The present experiments were designed to record electrical activity taking place along the auditory pathway before, during, and after prolonged sound stimulation, in order to observe whatever neurophysiological aft,ereffects may follow long-lasting stimulation. In addition to aftereffects, we found other phenomena which merit analysis in their own right.

In these experiments in waking animals, with neither reward nor punishment associated with loud, steady sound stimuli, responses in the form of sustained alterations in amplitude of averaged electrical activity were confined entirely to the classical auditory pathway
Something of the same sort appears to occur with respect to the visual system: light flashes presented to waking animals elicit responses in regions far removed from the classical visual pathway [12]
