A dynamic representation, per 5 min intervals, of stopping episodes with their dwell time, across two 30 min sessions of a Balb (top row) and a C57 mouse (bottom row). Bubble location represents location of stopping episode in arena and bubble diameter represents absolute dwell time in this episode. Note home base location at 9.00 O'clock, and increasing occupancy of the arena (Balb) versus decreasing occupancy (C57).
