Abstract
It is necessary to use experimental animals with behavioural, physiological and disease susceptibility pattern similar to man so that the results have a clinical predictive value. For such studies the non-human primate is the animal of choice. Rhesus monkey is a good choice for this purpose but information about its behaviour is fragmentary. In order to obtain a quantitative baseline data for psychopharmacological studies, a protocol has been developed to score various social and solitary behaviours in adult male and female rhesus monkeys. The study was conducted on rhesus monkeys in a social colony of one male and seven female living in a semi-restricted environment. The behavioural patterns were quantitated so as to compare effect on various components of behaviour. Aggressiveness and vigilance were prominent in the male while social affiliative behaviour was dominant in the female. Other behavioural responses were of similar magnitude in both sexes. It is however necessary to have data with some standard CNS active agents on these behavioural protocol. Therefore, initially the behavioural effects of amphetamine and haloperidol were studied. Significant effects observed following d-amphetamine (1-4 mg/kg, im); it induced dose dependent suppression of social behaviour (approach, contact, grooming), feeding, hypervigilance, stereotypy and oral hyperkinesia. On the other hand haloperidol (0.01-0.04 mg/kg, im) produced decrease in social and solitary behaviour and marked cataleptic posture. It is possible to quantitate drug effects on various aspects of behaviour of the rhesus monkey and to develop neuropsychitric models with the help of this protocol for use in study of drug effects on behaviour.
