Improve understanding the language of the brain by combining eye-tracking with fMRI

When you look at something, it goes into your eye, and it lands on your retina. The retina converts the information into a code of electrical pulses. This code of electrical pulses goes into the brain. The brain 'reads' these patterns of electrical activity to allow you to do things. To see, to hear, to feel, to smell, to reach for an object.
When we understand the language of the brain (the code/the patterns of electrical pulses), we are able to communicate with the brain in its language, things become possible that were not possible before.
Sheila Nirenberg shows how to create sight in people with certain kinds of blindness: by hooking into the optic nerve and sending signals from a camera direct to the brain.
