PSYCHOLOGICAL AND PHARMACOLOGICAL FACTORS CONTROLLING GASTRO-INTESTINAL MOTILITY.
Abstract
The report describes current findings in our continuing studies of the effects of response-contingent stimulation on g.i. activity. The results of the several experiments so far completed and analyzed suggest that the difference in effects in terms of the physical characteristics of the auditory stimulus, of sensory processes per se, or of motor output. Studie of effects of experimentally-produced gastric lesions on electrophysiological measures of g.i. activity are also continuing. Such a procedure obviously led to a possible confounding of the effects of histamine and of the anesthetic in the records obtained. We have developed a restrainer for use with the confinement procedure, which permits excellent electrophysiological recording. Pilot studies have been completed and the experiments proper are now underway. Other studies described in the report include: effects of variation in visual and auditory stimulation on g.i. motility, effects of alternate response-contingent and random auditory stimulation on g.i. motility, and effects of dextro-amphetamine sulfate on g.i. activity.
