Final answer:

True. The optic radiations do indeed project fibers from the lateral geniculate nucleus to Brodmann area 17, which is the primary visual cortex located in the occipital lobe.

Step-by-step explanation:

The statement that optic radiations project fibers from the lateral geniculate nuclei to area 17 is true. This part of the optic pathway is essential for the proper conveying of visual information from the eyes to the brain.

After crossing at the optic chiasm, the optic nerves continue as the optic tracts, which extend to the diencephalon and midbrain. The cells in the retina are developmentally connected to the diencephalon, and the optic tracts relay visual information principally to the lateral geniculate nucleus in the thalamus. From the lateral geniculate nucleus, axons project as optic radiations to the visual cortex in the occipital lobe, also known as Brodmann area 17. This connection enables the brain to process visual stimuli and is crucial for sight.

There are also connections to the superior colliculus, which plays a role in reflexive eye movements and orientation to visual stimuli. The decussation at the optic chiasm allows for the visual field information to be transmitted to the opposite side of the brain, a crucial design for binocular vision and visual field processing.
