  • Cross-sectional areas of major forebrain fibre tracts at the midsagittal plane were measured at the age of P0.5. Because the boundary between the corpus callosum and the hippocampal commissure of dyscallosal animals is difficult to determine, the combination of the two regions were compared. The means ± SEM are shown. n, Number of mice examined.
