Fig. 2.

Graphs showing the total number of parvalbumin⁺ cells (A) and of encephalopsin⁺ cells (E) in the striatum of the different experimental groups. Error bars indicate SEM. Photomicrographs of parvalbumin⁺ cells in the 3m (Fig. 1B), 12m (Fig. 1C), and 12m + PBM (Fig. 1D) groups and of encephalopsin⁺ cells in the 3m (Fig. 1F), 12m (Fig. 1G), and 12m + PBM (Fig. 1H) groups. Schematic diagram of the mouse forebrain (B′) adapted from a mouse atlas (Paxinos and Franklin, 2001). The red arrow indicates the approximate region where the photomicrographs of striatum (B–D and F–H) were taken from; the bold number corresponds to the plate number in the atlas. Scale bar = 100 μm. Abbreviation: PBM, photobiomodulation; SEM, standard error mean. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
