Differences in Sedative Susceptibility Between Types of Depression

Motivational Factors Associated with the Use of Cannabis (Marihuana)

“…The response to ^ock per cent change reflects the difference from onset of the unconditioned response to the most constricted point. 10 15 20 StifTiiilm Number The only significant effect found in vasomotor basal level was a change across trials {F = 2-51; p < 0-01), This represents a slight dilation across trials. There were no significant differences in basal level for drug vs. no drug condition or for reinforcement.…”

Dynamically rigid EEG and subtyping of depressive syndromes

“…Patients with endogenous depression show a prolonged alpha suppression to stimulation and during mental concentration which subsides after clinical recovery (Paulson and Gottlieb, 1961;Shagass and Schwartz, 1961;Whybrow and Parlatore, 1973). Patients with endogenous depression also show a lower sedation and a higher stimulation threshold than neurotic depressives (Shagass and Jones, 1958;Giberti and Rossi, 1962;Perez-Reyes, 1972). Melancholies but not patients with minor depression exhibit a state-bound increase of reaction time together with cognitive impairment (Cornell et al, 1984).…”

Some Preliminary Observations on a Questionnaire Technique for Classifying Depressive Illness: Its Relationship with Clinical Diagnosis and a Biological Technique for Depressive Classification

“…Inhibition Threshold Value (Perez-Reyes, 1968). This is a pharmacological measure of barbiturate drug tolerance which has been found to reliably and objectively distinguish between clinically defined groups of neurotic and psychotic depressives (Perez-Reyes & Cochrane, 1967;Byrne & Tottman, 1974).…”

“…This is a pharmacological measure of barbiturate drug tolerance which has been found to reliably and objectively distinguish between clinically defined groups of neurotic and psychotic depressives (Perez-Reyes & Cochrane, 1967;Byrne & Tottman, 1974). Neurotic depressives are found to exhibit a characteristically high barbiturate tolerance, while psychotic depressives exhibit a characteristically low barbiturate tolerance, both relative to normals (Perez-Reyes, 1968).
