Supplementary Figure 1: A typical bimodal neuron is unresponsive during control active head-on-body motion, and remains so during learning and catch trials.

A. Top row shows the head velocity during control trials, learning phase and catch trials overlaying a minimum of 5 trials. Bottom row shows the firing rates corresponding to the head movements above. Grey lines show individual trials and black lines show the average responses. B. The magnitude of head velocity error during control, learning, and catch trials. During the learning phase, the monkey initially made slower head movements as quantified by an increase in head velocity error. As learning further progressed, head velocity increased nearing control values as indicated by the striking decrease in head velocity error magnitude (light blue bars). C. Normalized sensitivity to corresponding head movements shown above. During the learning phase, the neuron remained insensitive as predicted by its response to active head-on-body motion before learning (light bluebars). Similarly, the minimal response for catch trials (red), was comparable to that measured for active head on body movements in the control condition and during learning. Data in B and C show average and error bars represent ±SEM.
