Moving speed and head direction. A, B, Examples of speed profiles for the left (cyan) and right (magenta) trajectories for a session (A) and all sessions combined (B). 1st T1/2, First half of the track; 2nd T1/2, second half of the track. C, Examples of head directions associated with the left and right trajectories for the first half, the second half of the track, and the choice zone (Ch) within a session. D, Head directions between left and right trials in each zone for all sessions for all the rats. E, Comparisons of head directions between left and right trials for each rat per session for each track zone (t test). Red squares represent a session showing a significant effect of head direction (p < 0.05). Vertical solid line indicates the boundary between the retrieval and acquisition periods in each rat. Note the minimal effects of head direction in the track area.
