Post Condition

Variation in the cage activity (measured simultaneously by a photoelectric relay system and an ultrasonic activity recorder) of six rhesus monkeys was directly related to the level of ambient illumination, whereas changes in noise level had only minimal effect. Activity changes were specific to the stimulus condition and no systematic residual post-condition effects were in evidence.
