The scatterplots display the relationships between measures of sociability and corpus callosum size for both BALB/cJ (n = 12) and C57BL/6J (n = 7) mice. Data for BALB/cJ mice are illustrated with gray circles, and data for C57BL/6J mice are illustrated with black triangles. A) The tendency of only BALB/cJ mice (n = 12) to sniff the social cylinder with the stimulus mouse inside (the cylinder sniffing preference change score) correlated with the size of their corpora collosa (corpus callosum index of abnormality), Spearman correlation coefficient 0.62, p = 0.02, one-tailed. B) The tendency of only BALB/cJ mice (n = 12) to spend time in the social chamber near the stimulus mouse (chamber preference change score) did not correlate with the size of their corpora collosa (corpus callosum index of abnormality).
