[ adjective ] (of drugs e.g.) able to excite or stimulate
Synonyms Used in print (E. Gellhorn, "Prolegomena to a theory of the emotions"...)Important as these differences are , they should not obscure the basic fact that by shifting the hypothalamic balance sufficiently to the parasympathetic side , we produce depressions , whereas a shift in the opposite direction causes excitatory effects and , eventually , maniclike changes . In other studies , loss of differentiation in previously established conditioned_reflexes resulted from repeated convulsive ( metrazol ) treatments , suggesting a fundamental disturbance in the balance between excitatory and inhibitory cerebral processes . It has further been shown that : ( 1 ) an experimental neurosis in its initial stages is associated with a reversible shift in the central autonomic balance ; ( 2 ) drugs altering the hypothalamic balance alter conditioned_reactions ; ( 3 ) in a state of depression , the positive conditioned_stimulus may fail to elicit a conditioned_reaction but cause an increased synchrony instead of the excitatory desynchronizing ( alerting ) effect on the EEG . In our attempt to interpret the emotions in their physiological and pathological range , we emphasized the importance of the degree of activity of the parasympathetic and sympathetic divisions of the hypothalamic system and their influence on the inhibitory and excitatory systems , respectively .
