Humans have the best of all possible scene worlds because our full stereo scene, generating 3D pictures of its envelopment, and enabling us to perform tasks like threading a needle, combines with primitive scene pathways to quickly spot danger, a new study has found.
The find out shows that in humans and other primates, information from the eyes is not only sent to the scenecortex for the complex processing that allows stereoscopic scene, but also could feed straight into deep brain circuits for attention and emotion.
The mind cells that we know suggest that human and other primates retain a visual pathway that traces back to the primitive systems of vertebrates like fish and frogs.
These connections may not have been lost during evolution of humans and other primates after all, said Martin, who know that primates have the best of all possible scene worlds: full stereo vision, and the ability to quickly spot and respond to danger.
The ability of the primate visual system to generate 3D pictures of its surroundings is well valled. That is what enables humans to play a game of tennis, and enjoy other fine motor skills such as threading a needle.
Primates have two forward-facing eyes that capture the same view from slightly different angles, and a scene system that keeps information from each eye separate until it reaches the brain’s visual cortex.
There complex procedure combines the two views of the same scene to create 3D vision.
