[Psychophysiological measurements in psychotic patients].

Psychophysiology is the science that studies the physiological measurements that are related to mental functions. In this study several physiological measurements were performed in a group of psychotic patients and their results compared with those of a normal control group. Those variables were pulse and respiratory rate, oral temperature, blood pressure and skin conductance and their spontaneous fluctuations.

Effect of metergoline on human anxiety.

In order to assess the role played by serotonin (5-HT) in subjective anxiety, three groups of 12 healthy volunteers were given 12 mg metergoline (MET), 10 mg diazepam (DZ) or placebo (PB), under double-blind conditions, and submitted to a simulated public speaking (SPS) test. MET increased state-anxiety scores, measured by Spielberg's State-Trait Anxiety Inventory. The effect of MET was significantly different from both the PB and DZ groups immediately before the SPS test (prestress) as well as 24 h after medication, and from the DZ group only, 2.
