Final answer:
The visual word form area or brain's letterbox is located in the occipital lobe and is essential for orthographic processing. Visual processing involves separate streams into the temporal and parietal lobes that identify visual stimuli and their significance, as well as locate objects in space and guide body movements.
Step-by-step explanation:
The area known as the visual word form area or brain's letterbox is located in the occipital lobe and is essential to the orthographic processor. Visual processing has two separate streams of processing: one into the temporal lobe and one into the parietal lobe. The ventral stream, which uses temporal lobe structures, identifies visual stimuli and their significance, while the dorsal stream locates objects in space and helps in guiding movements of the body in response to visual inputs.
