92 The panel followed a similar reasoning regarding Article XX (b) and found that measures aiming at the protection of human or animal life outside the jurisdiction of the

By exposing grass rats to short (8 h light and 18 h darkness, LD 8:16) or long photoperiods (16 h light and 8 h darkness, LD 16:8) respectively we manipulated the behavioral

The experiments of chapter 4 are aimed to explore the ability of rod- and cone photoreceptors to mediate the effects of light on SCN neuronal activity in the absence of

Changes in phase synchronization between individual cells have consequences on the amplitude of the SCN’s electrical activity rhythm, and these changes play a major role in

Phase advances in electrical activity rhythms recorded in SCN isolated from mice entrained to a short or long photoperiod in the presence of a running wheel.. (A and B) Examples

However, qualitatively different results were obtained when the proportion of neurons that receive the external signal drops below 1; specifically, the entrainment range is no

Here we investigate the role of classical photoreceptors by in vivo electrophysiological responses in freely moving animals to specific wavelengths of light (UV; λ max 365 nm,

To examine the role of cone photoreceptors in the magnitude of light-induced responses to the different wavelengths of light, we determined the light-induced sustained increases
