ABSTRACT
The majority studies of experimental neurosis and its somatic symptom in monkeys has involved the manipulation of various social, sexual, and alimentary response mechanisms. This approach to neurogenic stress has proved to be very fruitful in monkeys, which have highly organized social relationships. The subjects for the investigation were nine adult male hamadryas baboons. They lived in groups in large home cages allowing observation of a wide range of activities: motor, orienting–investigatory, alimentary, defensive, vocal and social. From the viewpoint of pathogenesis the immobilization neurosis in hamadryas baboons is a system-specific disorder, because the major factor in its establishment is transformation of conditioned and unconditioned aspects of eating. The functions of the alimentary system, into signals for the defensive dominant; one of the chief manifestations of the neurosis is the disruption of conditioned alimentary motor responses to normally conditioned alimentary stimuli.
