Fig. 5.

Interval maps for five different hippocampal traits on maps of Chr 1 derived from the BXD strains. Thex axes represent the entire genetic length of Chr 1.y axes represent values for the LRS computed at 1 cM intervals. A, Hippocampal volume; B, pyramidal cell layer volume (CA1–CA3); C, granule cell layer volume of the dentate gyrus; D, volume of the dentate gyrus (excludes part of the hilus); E,cross-section area of the mossy fiber projection (from Lassalle et al., 1999).
