Locomotor activity, habituation, and novel object exploration of prepubertal offspring prenatally exposed to chlorpyrifos (CPF) or peanut oil (PO). Graphs show total distance (A) as well as distance (B), number of entries (C), and time (D) in the center zone recorded during testing animals in 10-min sections in two consecutive days in open fields followed by 10-min exploration of a novel object in the center of the same fields. Graph and error bars are mean and SEM, respectively, of results from the same groups of animals as in Fig. 1B.
