Fig. 4. Representative actograms applied with various circadian rhythm experiment protocols. (A) Actogram (top) and lomb-scargle periodogram (bottom) of phase advance protocol with 6 hour light pulse applied at ZT 15 to ZT 21. (B) Actogram (top) and lomb-scargle periodogram (bottom) of phase delay protocol with 6 hour light pulse applied at ZT 9 to ZT 15. (C) Actogram (top) and activity center plot (bottom) of jet-lag protocol by 6 hour delay/advance. (D) and (E) Actogram of seasonal variation protocol by LD 16:8 and LD 8:16.
