WebUnder the T7 cycle, the same photic effects on sleep and waking amounts are observed for the first 1 h interval of the 3.5 h light pulses, with similar interaction with the time of day (Figure 3B, Supplementary Figure S3C; Supplementary Tables S5 and S6). Interestingly, when we examine the second period of the pulse, i.e., from 1 h to 3.5 h, we ...
A zeitgeber is any external or environmental cue that entrains or synchronizes an organism's biological rhythms, usually naturally occurring and serving to entrain to the Earth's 24-hour light/dark and 12-month cycles. sichuan chipset microelectronics co. ltdWebInsects express diverse behavioral rhythms synchronized to environmental cycles.
