Multicolored Compass Neurons (IMAGE)
Caption
The fly's neural compass (the multicolored donut) receives visual signals from many different neurons, allowing it to keep track of the fly's orientation in its surroundings. When a fly faces a particular direction, there's a bump of activity in neurons somewhere in the donut; as the fly turns, this bump moves around the donut like a compass needle. Here, subsets of these compass neurons in the donut, each of which would be active for a different heading, are labeled with different colors.
