Light-induced c-Fos expression un the SCN and behavioural phase shifts of Djungarian hamsters with a delayed aktivity onset

Original language description

C-Fos expression in the suprachiasmatic nucleus (SCN) and phase shifts of the activity rhythm following photic stimulation were investigated in Djungarian hamsters (Phodopus sungorus) of two different circadian phenotypes. Wild-type (WT) hamsters displayrobust daily patterns of locomotor activity according to the light/dark conditions. Hamsters of the DAO (delayed activity onset) phenotype, however, progressively delay the activity onset, whereas activity offset remains coupled to "light-on''. Althoughthe exact reason for the delayed activity onset is not yet clarified, it is connected with a disturbed interaction between the light/dark cycle and the circadian clock. The aim was to test the link between photoreception and the behavioral output of thecircadian system in hamsters of both phenotypes, to get further insight in the underlying mechanism of the DAO phenomenon. Animals were exposed to short light pulses at different times during the dark period to analyze phase shifts of th
