“…We found that 88% of the cercariae were shed between 11 a.m. and 3 p.m. and that the average pattern was of circadian type, with the average peak at 1 p.m., and representing 27% of the total number of cercariae of the day. The rhythms of emergence may be associated with environmental pressures on the parasite, especially those related to their definitive hosts.…”

“…A better understanding of the relationships among the body’s circadian rhythms, the brain’s hypothalamus, and a mutated gene holds enormous promise of improved care for the more than 36 million Americans who experience migraine (three times more common in women) and the number of people suffering from familial advanced sleep phase syndrome (FASP).…”

“…In this review, we consider evidence for how our performance ebbs and flows over fractions of seconds as we engage with sensory objects, over minutes as we perform tasks, and over hours according to homeostatic factors. We propose that rhythms of performance at these multiple tempos arise from the interplay among three sources of influence: intrinsic fluctuations in brain activity, periodicity of external stimulation, and the anticipation of the temporal structure of external stimulation by the brain.…”
