Fig. 4.

Color-encoded diffusion directions at $300\mathrm{\mu }\text{m}$ and 500 directions. The white dotted lines indicate the correspondence between axial (a), sagittal (b), and coronal (c) slices. Orange arrowheads point at the fimbria, yellow arrowheads at the alveus, and pink arrowhead at the lacunosum-molecular layer. The color-encoding cross at the bottom left of the image depicts the direction of largest displacement probability orientation. $A\text{anterior}$, $P\text{posterior}$, $M\text{medial}$, $L\text{lateral}$, $S\text{superior}$, $I\text{inferior}$
