In chronic experiments on insectivores (hedgehogs), rodents (rabbits) and primates (monkey, macaca rhesus) the peculiarities of elaboration delayed conditional reflexes were investigated.The experiments carried out using food model of Pavlov classicical method with simultaneous registration of vegetative and somatic components of condional reflexes. It was shown that in hedgehogs the elaboration of delayed condional reflexes (type of shortmemory) be required too many connections of conditional stimulus with unconditional ones to receive short term (S-10 s) delayed conditional reflexes. In rodents (rabbits) the formation of delayed conditional reflexes is possible to elaborate conditional reflexes with delay about IS-25 s after swithching on the conditional stimulus and this kind of conditional reflexes is retained as long as several days. In monkeys the different type of the shortand longterm types of memory were possible to elaborate within of one or two experimental days with delay of conditional stimulus for several tenth of second. It is necessary to point out that after interruption in work with delayed condional reflexes they may be retained easily within 3 5 months. The experiments on monkeys was shown that administration of neuropeptide vasopressin accompanyied by facilitatory effect on long-term memory. These findings show that possibility to elaborate more prolonged of delayed conditional reflexes is increased with ascending row of mammals. 168
