Expression of PER1 in the LSD. (A) Photomicrographs of representative sections at nursing time and at 8h after nursing in the Nursing ZT03 group. Note the density of PER1-ir cells 8h after nursing. LV, lateral ventricle, CC, corpus callosum. Scale bar 100 μm. (B) PER1-ir cells in Control, Nursing ZT03 and Nursing ZT19 groups; ** Denotes significant difference between higher and lower values within the same group.. ** P < 0.001. Values are mean ± SEM. The black and white bar at bottom represents the LD condition. (C) Cosinor analysis indicates a significant rhythmicity of PER1-ir cells in Nursing ZT03 and Nursing ZT19, but not in Control group.
