This is a question from Kaplan notes

A 63-year-old laborer was brought to the ER by a coworker who found him wandering aimlessly. The driver has no recollection of how he came to be here. The last thing he remembered was that he was riding to work when he smelled something burning; then he remembered seeing large trunks running up and down the road. The driver was immediately admitted where he began suffering from epileptic seizures and olfactory hallucinations. A neurological examination revealed a visual field deficit. This deficit is most likely to be
A. a homonymous hemianopsia
B. an inferior quandrantanopsia w/ macular sparing
C. psychic blindness
D. anopsia
E. a superior quandrantanopsia

E- Olfactory hallucinations means the lesion is in temporal lobe. The fibers from the inferior retina must pass into the temporal lobe by looping around the inferior horn of the lateral ventricle. These fibers, which carry information from the superior part of the visual field, are called Meyer's loop. A lesion in the temporal lobe that results in damage to Meyer's loop causes a characteristic loss of vision in a superior quadrant.
