[Behavior-parameter characteristics of a socio-emotional, neurosis-causing process in rhesus monkeys].

Changes in relationships between behavioural repertoire, motility, and diastolic blood pressure were studied in rhesus monkeys under socio-emotional stress exposure. The frequency of behavioural patterns is a function of diastolic blood pressure. The initial stage of stress (normal BP) induced affective manifestation of aversion, tendency of spatial changeability and reactions of shock-avoidance. The late phase of stress (elevated BP) is associated with increased communicative control of social distance and physiological alterations: increased arousal, lability of autonomic functions and itching. The behavioural patterns of environmental integration were decreased with elevated diastolic blood pressure, in favour of comfort actions.
