Nervous system
Looks like
A short band of fibres running from the optic tract region to the superior colliculus, beside the thalamus.

Carries visual signals from the eyes to the superior colliculus and pupil-reflex centres.
Keeping it well
Not examined on its own; it matters mainly as a landmark in the visual pathway.
