After the optic chiasm, do inferior fibers travel more medially or laterally?

Explanation:
After the chiasm, the optic tract preserves a map of the contralateral visual field. The fibers corresponding to the inferior part of the visual field are positioned toward the lateral side of the tract, while fibers for the superior part sit more medially (and route toward the temporal Meyer's loop). So the inferior-field information travels more laterally after the chiasm.
