Operant conditioning of eye movement in the monkey (Macaca nemestrina).

With the horizontal electrooculographic potential as the operant, four monkeys (Macaca nemestrina) were conditioned to move their eyes at high and low rates by initial use of fixed-ratio schedules of reinforcement, followed by a changeover to multiple schedules of fixed-ratio reinforcement and discriminated differential reinforcement of low rate. These differences in rate of eye movement were not observed in a control animal given the same patterns of discriminative stimuli and deliveries of the reinforcing agent independent of its eye movements.

Energy conservation and sleep.

Phylogenetic and ontogenetic associations between sleep and endothermy are consistent with the hypothesis that sleep evolved in conjunction with endothermy to offset the high energetic cost of endothermy. The electrophysiological and thermoregulatory continuum of slow wave sleep, circadian torpor and hibernation substantiates a primordial link between sleep and energy conservation. Sleep constitutes a circadian and circannual rhythm of hypometabolic adaptation to biospheric energy cycles that is usually entrained through light-mediated suppression of melatonin secretion. When energy stores decline, energy is conserved by lowering Tb proportionally during sleep or by increasing the daily duration of sleep.
