Fig.1: Imaging a mouse brain slice. (IMAGE) Osaka University Caption A multicolor image of a mouse brain slice with two regions indicated by light blue squares, namely, the cerebral cortex (A) and the hippocampus (B). These are displayed in the whole-brain image (left) and digitally magnified 5x (middle). The local regions of light blue squares in the 5x images are further digitally magnified five times (right). Red, green, and blue represent the fluorescence due to a red fluorescent protein expression in excitatory projection neurons, a green fluorescent protein expression in inhibitory interneurons, and Hoechst 33342 attached to nuclear DNA, respectively.
