Fra-2- and TH-ir co-localization in the PMM. (A) Dark (arrowheads indicate single-labeled TH-ir), (B) blue (arrows indicate co-localized neurons, arrowheads fra-2-ir), (C) white (arrows indicate co-localized neurons, arrowheads fra-2-ir), (D) dark conditions (arrowheads indicate single labeled TH-ir). (E) Only white and blue light conditions elicited fra-2 expression within TH-ir neurons. Red and dark conditions showed significantly fewer fra-2/TH-ir co-localized neurons. 3v = third ventricle, ***P < 0.001, Bar (A) = 50 μm, Bar (B,C,D) = 100 μm.
