Light information reaches the suprachiasmatic nucleus via the:

A) lateral geniculate pathway.
B) occipital cortex.
C) thalamic pathway.
D) retinohypothalamic pathway.

Suprachiasmatic Nucleus

A small area within the hypothalamus that regulates circadian rhythms.

Retinohypothalamic Pathway

A neural pathway connecting the retina to the hypothalamus, involved in regulating circadian rhythms based on light exposure.
