Perinatal low-dose PBDE-47 exposure induces memory impairments in adult rats. Maternal rats were treated with vehicle (corn oil) or PBDE-47 (0.1, 1.0, 10 mg/kg/day) from pre-pregnancy until weaning and female offspring rats were raised until PND 88. (A) Schedule of PBDE-47 exposure. (B) Representative traces on the fourth day in the PNT. (C) The mean escape latency, swimming distance, and swimming speed to platform in the PNT. (D) Representative traces in the SPT. (E) Distance, time spent in the target quadrant (%) and the number of platform crossings in the SPT. The data are presented for six rats each group. *P < 0.05 versus the control group.
