TY - JOUR PY - 1940// TI - Neurophysiological and psychological changes induced by certain drugs: I. Responses to electrical stimulation JO - Journal of experimental psychology A1 - Fowler, O. D. SP - 657 EP - 668 VL - 27 IS - 6 N2 - In this study measurements of rheobase, chronaxy, and effects of repeated stimuli on intensity and duration, with reference to the chronaxy point, were made on peripheral nerve and muscle. The subjects were 8 psychopathic cases and 1 student. The measurements were made before and after the injection of the following drugs: adrenalin, mecholyl, cocaine, and sodium amytal. No tendency for any of the drugs to produce a consistent change in any of the measures was found. No conclusions could be drawn as to the possible influence of psychopathological states.
