[Technique for registration of auricular pulsogram in macaca mulatta monkeys]

An upgraded technique for registration of auricular pulsogram in monkeys (Macaca mulatta) has been proposed to study shifts in the common artery bed. The measurement is made with a photo-electrical sensor taped to the cartilage of the floor of the auricle and secured with a special cap and helmet of elastic net, and a system for data transfer from the sensor to a register enhanced by preamplifiers. Potentialities of the technique are exemplified by the investigation of Macaca mulatta's tolerance of +Gz loads.
