Phase resetting in duper hamsters: specificity to photic zeitgebers and circadian phase.

Journal of biological rhythms - 1 Apr 2015

Manoogian Emily N C, Leise Tanya L, Bittman Eric L

Abstract excerpt

The duper mutation in Syrian hamsters shortens the free-running period of locomotor activity (τDD) to about 23 h and results in a type 0 phase-response curve (PRC) to 15-min light pulses. To determine whether exaggerated phase shifts are specific to photic cues and/or restricted to subjective night, we subjected hamsters to novel wheel confinements and dark pulses during subjective day. Small phase shifts...
