Human brain
A brain is an organ that processes information. In humans, eyes connect to it through optic nerves. Perception happens using a brain. (There is consciousness in a brain.)
A BCI can connect to a brain.
It can be interfaced with a computer system.
A brain has a visual cortex at the back.
Connecting to the brain[edit]
Connecting to the brain is the process of connecting a computer system to a brain.
It can be done using direct neural connection, or by going through the five senses.
Direct connection, such as neuralink, can read data and theoretically write data. Going through the senses using a visual display can write data much faster.
Perception[edit]
A perceptual space is a set of perceptions that a human can have. A human perceptual space is a set of all possible perceptions that can happen in a human brain.
The human perceptual space is largely visual. About eighty to eighty-five percent of our perception, learning, cognition, and activities are mediated through vision.[1] Almost the entire lower half of the cerebral cortex is for processing visual information.[2]
Related concepts are retinotopic mapping and the cortical homunculus.
Retinotopy is the mapping of visual input from the retina to neurons.[3]
Cortical magnification is a measure of how many neurons in an area of the visual cortex are responsible for processing a stimulus of a given size.[4]
