Final answer:
The two visual streams from the primary visual cortex are the ventral stream, which projects into the temporal lobe for object identification and memory integration, and the dorsal stream, which projects into the parietal lobe for spatial awareness and movement coordination.
Step-by-step explanation:
Two functionally different visual streams project from the primary visual cortex to other areas of the brain involved in visual processing. After visual signals reach the primary visual cortex at the occipital lobe, they diverge into two distinct pathways or streams. The ventral visual stream flows into the temporal lobe, engaging structures that are crucial for the identification of visual stimuli and their significance, also playing a role in integrating visual information into long-term memory.
In contrast, the dorsal visual stream projects into the parietal lobe, interfacing with the somatosensory cortex, which is essential for spatial awareness and coordinating body movements in response to visual cues. These two streams are critical for understanding visual information's complexity and manifest different aspects of visual processing—the 'what' and 'where/how' aspects, respectively.
