Light restores baseline trajectory profiles. Fractal dimension (a) and trajectory bias (b) after loss of illumination, either with constant dark (black circles, N = 25) or when full-field illumination was restored after 30 s of dark (orange triangles, N = 22). Dotted line indicates mean for larvae tested under constant illumination (N = 25). * P < 0.05 for corresponding time-points between larvae in constant dark versus larvae with illumination restored.
