Methodological specifications.

A: The rats' position on the 140 cm long maze (y-axis) over time (x-axis). 8 consecutive trials are shown. B (left): Distribution of accelerations for all rats across all recording sessions. Max acceleration = 102.70 cm/s2; max deceleration = −105.74 cm/s2 (count units = ×105). B (right): Distribution of speeds for all rats across all recording sessions during acceleration and deceleration (count units = ×104). C: The rats' speed (black) and acceleration (red) as a function of position on the maze for an entire recording session for one rat (∼5 minutes). Acceleration is shown in both running directions in order to emphasize the similar distribution of accelerations/decelerations. D (top): Speed (black) and acceleration (red) as a function of time. 8 consecutive trials are shown in order to visualize the relationship between speed and acceleration/deceleration. D (bottom): A closer look at the first 12 seconds of the top signals, now only the first 3 consecutive trials are shown. E: Relationship between acceleration and theta amplitude (top) and deceleration and theta amplitude (bottom) as a function of “low” and “high” speeds.
