Neurons Controlling Spontaneous Zebrafish Swimming Behavior (IMAGE) eLife Caption Mapping neurons that control spontaneous swimming behavior across the zebrafish brain. Gray and cyan are anatomical markers, with cyan showing neurons that project to the spinal cord. The green, red, and blue cells result from functional mapping, where green cells control leftward turning, the red cells control rightward turning, and the blue cells are tuned to forward swimming. These populations of neurons guide spontaneous zebrafish behavior when external environmental cues are lacking.
