For this purpose, we recorded the electrocardiogram of two male rhesus monkeys seated in a primate chair while the experimenter groomed their mouth, chest, or arm.In addition to the numerous studies related to allogrooming, also the behavioral and physiological impact of grooming conducted by humans on monkeys or other animals has been explored. However, there is no evidence regarding the psychophysiological consequences of human grooming on monkeys at the autonomous system level. Although the primary biological function of allogrooming is to take care of the body surface of others, many studies demonstrated its social function in many animals 1 — 8 and especially in non-human primates [see Ref. The company seems poised to continue their growth efforts in the second half of the year. The criteria to determine whether the monkeys learned the procedure were: 1 when the monkeys learned to sit in the primate chair, i. Many human studies suggested that the HRV is an important indicator for the non-invasive assessment of autonomous nervous system activity in healthy people 41 — 44 , in patients with mental diseases 45 , 46 , cardiac dysfunction 47 , 48 , and stress Concerning non-human primates, Taira and Rolls 40 demonstrated that receiving grooming from humans is a positive reinforcement in operant conditioning for rhesus monkeys. Can the company carry its momentum on into the second half of the year?
Inside the cage, each monkey had access to toys, mirrors, and swings. The well-being and health conditions of the monkeys were constantly monitored by the institutional veterinary doctor of the University of Parma Italy.
