Figure 4

Trajectory of the stria terminalis. Panel (A–D) show high-resolution MR images at four different locations indicated in Figure 1. The stria terminalis (st) and the fornix (fx) have spatially similar, but anatomically distinct, trajectories. For the entire trajectory, the stria terminalis remains in close proximity to the caudate. Compared with the fornix, the poorly myelinated stria terminalis has lower fractional anisotropy (FA) value and higher T2 intensity, more similar to that of gray matter structures. Scale bars, 5 mm. Abbreviations are the same as in Figure 2, with the addition of: Cau, caudate; Cau-t, tail of caudate; HT, hypothalamus; LGN, lateral geniculate nucleus; Pul, pulvinar; Tha, thalamus; cc, corpus callosum; cg, cingulate; ic, internal capsule; mtt, mammillothalamic tract; or, optic radiation; sm, stria medullaris.
