Simultaneous recording of the activity of the command neuron AVB and the locomotory behavior of a freely moving animal. Upper left: video output of the spotting camera. The bright ring is reflectance from the 63× objective beneath the preparation. Upper right: x-y trajectory of the tracking target with a cursor indicating the x-y location at the time of the current frame in the movie. Lower left: video output of the calcium imaging camera. Lower right: time course of the AVB emission ratio (upper trace) and velocity (lower trace) with a cursor indicating the ratio and velocity at the time of the current frame in the movie (blue, forward; red, reverse).
