Circling in Validation mice on orbit. (a) Table 2 Sequence of milestone appearance and operational definitions in the emergence of circling behavior. (b) Quantification of circling behavior. Top image. Average number of mice circling by cohort (Filter Left or Filter Right) normalized to total video duration. Middle image. Average number of laps per second per mouse by cohort (Filter Left or Filter Right) normalized to total video duration. Bottom image. Estimated average circling speed (m/s) [Formula: Estimated lap distance traveled assuming route is an average between an oval and a rectangle/number of video frames traversed in one lap * frame rate (29.97 fps)] was converted to mph (m/s * 2.2369). (c) Percent time spent circling (per each of the five mice within each of the two Validation FLT groups) averaged across 8-day mission quarters. (d) Around-the-clock analysis of circling behavior in Validation mice. Top image. Average (mean +/− se) number of mice circling per second averaged across light and dark cycle phases derived from video segments acquired hourly beginning on L + 30. Bottom image. Average (mean +/− se) laps per second normalized for numbers of Validation mice circling.
