Question

Quizplus · Accepted Answer

The fibers in the optic tracts primarily project to the thalamus, specifically the lateral geniculate nucleus (LGN), which is involved in visual processing and relaying information to the cortex. While the superior and inferior colliculi are also involved in visual processing, they primarily receive input from the optic tectum and are not the main targets of optic tract fibers. The suprachiasmatic nucleus of the hypothalamus is involved in regulating circadian rhythms and receives input from the retina, but this input is primarily via the retinohypothalamic tract, not the optic tracts.
