How Do Our Brains Semantically Map the Things We See?


At last- neurological research that doesn’t take a brain surgeon to understand it! Researchers from the Gallant Lab at UC Berkeley placed subjects under an MRI while they watched videos with thousands of items labeled by words. They were able to map which part of the brain was stimulated by each word and noticed that similar objects were grouped close to one another. With their research data, they created the first interactive map of how the brain organizes these categories. Interestingly, all of the different people shared a similar semantic map. The implications of this study will be huge for diagnosing and treating brain disorders. Once the visual systems of the brain are understood, researchers can begin to map the cognitive systems that mediate complex thought.
