Novel cage activity levels quantified using an open field photobeam activity system (PAS) in control mice (n = 20) and mice that were exposed to asymptomatic doses of domoic acid via intraperitoneal (IP) injection once a week for 25 weeks (n = 20). Chronically exposed mice were significantly more active than control mice after 25 weeks of low-level domoic acid exposure, but returned to control levels after a nine-week recovery period with no toxin exposure. Statistically significant p values are shown; ns = not significant
