CNE_23191_sm_SuppMovie1.wmv5959KMovie 1. This movie provides four examples of approach, response, and retreat events used for electrophysiological analysis. Onset and offset times are marked for each behavior. Approach onset, retreat onset, and retreat offset were determined using frame-by frame video scoring. Note that approach offset, response onset, and response offset were determined via electronic timestamp of photocell beam breaks. These timepoints were displayed in this video for illustrative purposes only.
CNE_23191_sm_SuppMovie2.wmv4842KMovie 2. This movie provides examples of the pre-approach movement and approach events exhibited by one rat. Two neurons exhibited changes in FR during these behaviors (Figure 13A,B). Onset and offset times are marked for both behaviors.
