Middle-aged rats reared in an enriched environment displayed rapid habituation to the Open Field test. (A) Distance traveled over time, insert: total distance traveled; (B) number of rears over time, insert: total number of rears; (C) time spent in the central area over time, insert: total time spent in the central area; (D) ratio central / total distance traveled over time, insert: Ratio central / total distance traveled during the entire OF session. CTL SE, vaginal delivery rats reared in standard environment; C+ SE, rats born by cesarean section reared in standard environment; PA SE, rats born by cesarean section + asphyxia reared in standard environment; CTL EE, vaginal delivery rats reared in enriched environment; C+ EE, rats born by cesarean section reared in enriched environment; PA EE, rats born by cesarean section + asphyxia reared in enriched environment; CTL, vaginal delivery rats; C+, rats born by cesarean section; PA, rats born by cesarean section + asphyxia; SE, standard environment; EE, enriched environment. Data are expressed as the mean (A–D) or the mean + s.e.m. [inserts] of n = 12. In (A–D) error bars are omitted for clarity. ***p < 0.001 and **p < 0.01 compared to groups reared in SE, ##p < 0.01 and +p < 0.05 compared to the first 5 min time bin.
