Figure 2. Stereotypy of vibrissa structure and sampling behaviors during the task.

Figure 2

A. Schematic of behavior apparatus B. Vibrissa lengths by arc in A to D rows, estimated from high speed videos (N=4) from one session with Rat 4B (dots, one for each video and vibrissa), and comparison to ex vivo lengths from Table 2 of [13] (circles), showing consistent gradient of length with arc position. C. Probabilities that a vibrissa in a given arc did (black) or did not (white) make contact with the surface during the same trials. Total probability is below one due to vibrissae whose contact category could not be conclusively determined from the video. At least one vibrissa in each of the 2, 3 and 4 arcs made contact in every trial (not shown).
