Classical conditioning of blood pressure in Macaca mulatta with cardiac rate controlled.

摘要: The interaction of heart rate and blood pressure responses was studied in four male rhesus monkeys (M. mulatta) during classical delay conditioning extinction. During initial sessions, held constant by means an external cardiac pacemaker; follow-up the free constraint. Observations were made after these (a) several sessions given over to continued training while different pacing rates effect; (b) a series extinction which paced unpaced; and, (c) when CR simulated manipulation pacer with no conditioned or unconditioned stimuli present. Throughout all systolic diastolic pressures measured at each beat. It found that largely unaffected changes prevented acquisition. Extinction also seen proceed relatively unimpeded fixed frequency. postacquisition tested did not produce any significant differential effects CRs. Simulated CRs accompanied small pressures, sometimes opposite direction from observed unpaced trials.
