This image shows two pairs of β-lobe neurons (one colored here blue, one orange), which process olfactory information in the locust brain. Also visible in color (toward the top) are the mushroom bodies, brain areas associated with learning and memory. The β-lobe neurons were visualized by intracellular injection with neurobiotin. The mushroom body was visualized by mass fill with a dextran dye and imaged so that deeper parts are more blue and parts closer to the surface are red. The image is a composite of several different confocal pictures registered to the same locust brain (light gray).
