on our task, neither gamma-50 or gamma-80 modulation can be straightforwardly explained by a relationship to running speed. For gamma-80, the reward-approach ramp observed on the segment between the final choice point and the first reward site (T4-F1) is accompanied by a similar speed profile to that of the F2-S segment, where no gamma-80 ramp is seen. Similarly, elevated gamma-50 power persists well into the F2-S segment, but is absent on T4-F1.
