Brain Remains Active During Sleep, Continues Simplified Functions

Brain Remains Active During Slumber, Continues Simplified Functions

A combined team of researchers from the University of Cambridge and Ecole Normale Supérieure, a research institution in Paris, have found that even during sleep, our brain can still classify words. According to the researchers, when people practice simple word classification tasks before nodding off—knowing that a "cat" is an animal or that "flipu" isn't found in the dictionary, their brains still continue to make those classifications even in the unconscious state of mind.
