Age and strain effects on time spent in open quadrants of an elevated zero maze. Early adolescent (a), middle adolescent (b), late adolescent (c), and adult (d) animals were examined for baseline differences in the total time spent in the open quadrants of the zero maze. A main effect of strain (p = 9.0 × 10−12) but not age was detected for the time spent in the open quadrants. C57 animals spent more time in the open quadrants relative to C3H animals across all age groups. Data represent mean ± SEM.
