Description
Summary:ABSTRACT The relation between cardiac activity and motor activity wan investigated in a monkey with normal blood pressure working on a 10‐sec Sidman avoidance schedule. The monkey's lever‐pressing; activity and his blood pressure, measured from an arterial catheter, were simultaneously recorded on a dynograph. A total of 2536 lever presses were recorded in there test periods. and each response was related to the phase of the blood pressure wave m which it occurred. A Spearman rank correlation coefficient of 0.63 was found between the time of onset of the response and the height of the pressure wave when the data were grouped into 10, periods and adjusted for a 110‐meser delay. These results were interpreted as additional support for the idea that the autonomic afferent fibers maintaining homeostatic circulatory adjustment can also modulate midbrain reticular activity and thus influence the expression of voluntary behavior.
