Abstract

Hippocampal rhythmic slow activity (RSA) and its relation to somatomotor activity and heart rate (HR) were assessed in 128 sec observation periods in 2 monkeys under three behavioral conditions, i.e., look (at experimenter); reach (for food); struggle (against restraint); and one control condition (no monkey-experimenter interaction) which was interspersed between each behavioral condition. Two measures of hippocampal activity (in addition to HR) were taken: (1) percent RSA/128 sec (from filtered, 4-8 Hz, integrated signal); (2) Spectral analysis of unfiltered activity from first 10 sec of each observation period. Spectral analyses were done over 1-3, 4-8, 9-12, 13-20 Hz bands. Results showed that the greatest increases in RSA and HR were present during intense somatomotor activity (struggle condition) for both animals. RSA was variable during the reach and look conditions. RSA and HR were highly correlated under all conditions. Spectral analyses showed that reliable changes in energy were limited to the 4-8 Hz band. Results are discussed in terms of RSA-HR-somatomotor relationships in primates and infraprimates.
