How Neurons Transform Raw Visual Input

The world constantly bombards our senses with information, so how does our brain makes sense of these information? For example, what processes are there in our brain that enables us to identify the object in front of us? Neuroscientists now know the answer.

In work published in Nature Neuroscience, MIT neuroscientists have identified a brain circuit in mice that distills “high-dimensional” complex information about the environment into a simple abstract object in the brain.
“There are no degree markings in the external world; our current head direction has to be extracted, computed, and estimated by the brain,” explains Ila Fiete, an associate member of the McGovern Institute and senior author of the paper. “The approaches we used allowed us to demonstrate the emergence of a low-dimensional concept, essentially an abstract compass in the brain.”
This abstract compass, according to the researchers, is a one-dimensional ring that represents the current direction of the head relative to the external world.
