Figure 3: Hunger Regulates Eye Position and Action Selection.

A. Mean eye vergence per interbout (like Figure 1I) for observations in first 10 minutes of testing, shown separately for fed and starved groups. Solid vertical lines indicate local histogram peaks. B. Fed fish display wider eye divergence preceding exploring bouts and J-turns, but not pursuits, aborts, and strikes (bout-types ordered as in C). See Figure S3 for eye kinematics associated with each bout-type. C. Log₂ of relative bout-type abundances (starved / fed) during first 40 minutes of testing. D. Interval durations (mean ± SE) following each bout-type for fed and starved groups (first 40 minutes of testing). E. Log₂ of relative bout-class abundances (starved / fed) in 10-minute bins.
