Question

Quizplus · Accepted Answer

Ganglion cells from the left half of both eyes (left visual field) project to the right hemisphere, and those from the right half of both eyes (right visual field) project to the left hemisphere. However, the question's phrasing implies a focus on the left halves of both eyes, which would both project to the right hemisphere. The correct interpretation based on standard visual pathway knowledge should be that both left halves project to the opposite hemisphere, which would be the right hemisphere. However, given the options provided and the likely intent behind the question, the best match (though seemingly contradictory to standard anatomical understanding) is option A, indicating a possible error in the question's construction or a misunderstanding. Normally, the correct physiological response would involve contralateral projection (left visual field to right hemisphere and vice versa), but the options do not reflect this accurately.
