Question

which structure receives visual information before it reaches the visual cortex? (figure 14 - 20)
supra - optic nucleus of the hypothalamus
medial geniculate body of the thalamus
lateral geniculate body of the thalamus
ventral nucleus of the thalamus
paraventricular nucleus of the hypothalamus

Explanation:

The lateral geniculate body of the thalamus is a key relay station for visual information. Visual signals travel from the retina through the optic nerve, optic chiasm, and optic tract to the lateral geniculate body. From there, they are projected to the visual cortex. The supra - optic and paraventricular nuclei of the hypothalamus are mainly involved in hormone regulation (e.g., antidiuretic hormone). The medial geniculate body is related to auditory pathways. The ventral nucleus of the thalamus is more associated with motor and sensory (other than visual) functions.

Answer:

lateral geniculate body of the thalamus
