Caption: Upper panel shows fluorescently labeled neural projections in a larval zebrafish from the habenular nuclei in the forebrain to the interpeduncular nucleus in the midbrain, a pathway known to be involved in nicotine addiction. The lower panels demonstrate neural activity (black cells) in cross sections of brains following exposure of adult zebrafish to control water (left) or to water containing nicotine (right).
