Researchers at the University of California, Berkeley have created a map showing how and where the brain categorizes the actions and objects we see every day. The study began by taking five human subjects and placing them in an MRI machine while they each watched two hours of movie trailers. Each of the trailers had been analyzed to track the different objects and types of motion present — a leaf holding still, or a butterfly flying, for example. The MRI then allowed the researchers to track the blood flow in the brain to see what areas were being stimulated during the screenings.
They then used regression analysis — a statistical technique that is able to determine relationships between different events — to determine how the...
