The brain regions involved in pineal ‘color’ detection

Caption

Light is detected by both the eye and the pineal organ. The light-sensitive opsin PP1 in the pineal cells senses the balance of ultraviolet and visible light and converts it into neural signals. These signals are processed in the tegmentum, where they regulate the fish’s up and down swimming behavior.
