Abstract

In four experiments, performed at different months throughout the year, a significant daily rhythm in dopamine receptor binding has been observed. This rhythm is endogenous, as it persists in the absence of time cues. Striking differences in wave form, amplitudes, and timing of peaks during the year suggest that the endogenous rhythm undergoes seasonal variations.
