Influence of neuropeptides on the processes of higher nervous activity in primates. The action of cyclic analogs of enkephalins on the behavior of the lower monkeys.

The effect of two cyclic enkephalin analogs (IVS-43 and IVS-46) on the group and individual behavior of rhesus macaques and hamadryas baboons has been studied. A pronounced influence of IVS-46 on competitive and operant goal-directed behavior of the monkeys was identified.

[The effect of neuropeptides on the processes of higher nervous activity in primates. The action of cyclic analogs of enkephalins on the behavior of lower monkeys].

The influence of 2 cyclic enkephaline analogues (IVS-43 and IVS-46) on group and individual behaviour of rhesus and baboon monkeys was studied. The effect of IVS-46 on competitive and operant goal-directed behaviour of the monkeys was expressed. Possible mechanisms of functional reorganization of the higher nervous activity of primates under the influence of neuropeptides are discussed.

[The comparative action of relanium and oxytocin on higher nervous activity in lower monkeys].

Effects of relanium and oxytocin on higher nervous activity was studied in four rhesus monkeys (Macaca mulatta) and two baboons (Papio hamadryas). During observation of the animals in enclosure tranquilizing effect was seen only after relanium administration. Under the same conditions oxytocin practically did not change the general behaviour pattern of monkeys.
