Figure 3. Asymmetry in the mean (±SEM) intensity of Per1 expression among hamsters maintained in LL in experiment 2.

Figure 3

Per1 expression was lateralized in cases in which the high to low ratio of Per1 expression exceeded that in non-split controls. The high to low ratio of Per1 expression is illustrated in the (A) AVP-expressing cells of the SCN, (B) HCRT-expressing cells of the LH/DMH and (C) TH-expressing cells of the LC. Consistency of lateralization to the high Per1 expressing SCN was assessed by the ipsilateral to contralateral ratios of Per1 expression in (D) HCRT-expressing cells of the LH/DMH and (E) TH-expressing cells of the LC. * p<0.05 vs. C; χ p<0.05 vs. 9 h before activity onset.
