Comparison of sociability and social novelty preference among Disc1 L100P/L100P, L100P/+, and +/+ littermates. (A) Sociability: mean time spent near the empty cage (Empty) or the cage containing the unfamiliar mouse (Stranger 1) (left), and the number of entries into each chamber (right). (B) Mean time spent near the cage containing the first unfamiliar mouse (Stranger 1) or a new unfamiliar mouse (Stranger 2) (left), and the number of entries into each chamber (right). All values are expressed as mean ± SEM for each group. ^*p < 0.05, ^**p < 0.01 or ^***p < 0.001 versus time spent near the unfamiliar mouse (Stranger 1). ^###p < 0.001 versus the number of entries into the center chamber.
