Note that in measures of anxiety, the Nlgn3+/– mice raised with Nlgn3–/– mice were indistinguishable from Nlgn3+/– mice raised with Nlgn3+/+ littermates (Fig. 7B–D), suggesting that the behavior of Nlgn3–/– mice does not affect the anxiety of their littermates. This evidence concerns the gene NLGN3 and Anxiety.
