WebMar 1, 1999 · Here, we examined the effect of unconditioned and conditioned aversive stimuli on photic responses within the primary visual cortex in rats using expression of the transcription factor Fos as a functional marker of neuronal activation. 16 In previous studies carried out within the circadian visual system, we found that photic induction of Fos ... 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 ...
