A three-dimensional reconstruction of the entire depth of the front part of the brain (forebrain) of an intact living adult zebrafish imaged with three-photon microscopy (3PEF). The green color indicates very many labeled neurons (small dots), which are expressing a gene for a fluorescent marker of cells. The magenta color shows other features such as the skull and neuronal processes. The movie begins with the front of the head of the fish facing left and the top of the head up. Credit: Fetcho Lab
