Axial images through Meyer’s loop.

A, Reformatted image obtained in an axial plane parallel to floor of the temporal lobe is advantageous for showing Meyer’s loop (yellow) coursing along the lateral wall of the temporal horn (T). Of note is the most anterior extent of Meyer’s loop, which is at the level of the amygdala (A) but does not reach the level of the tip of the temporal horn (compare with Fig 12A). The undissected optic radiation (arrows) is passing toward the occipital lobe. H indicates the hippocampus.

B, Oblique (+17°) axial image at the level of the lateral geniculate body (arrowhead), shows Meyer’s loop (arrow) crossing over the region of the roof of the temporal horn, which is below this image level. This relationship is more obvious on the coronal images in Figure 12B and C.
