A new paper challenges a decades-old theory in neuroscience: Split brain: divided perception but undivided consciousness
According to the famous work of Roger Sperry and Michael Gazzaniga, “split brain” patients seem to experience a split in consciousness: the left and the right side of their brain can independently become aware of, and respond, to stimuli. Split brain patients are those who underwent surgery to sever the corpus callosum, the nerve tract connecting the two hemispher ...read more

The ...read more

The actual bite happened in less than a second. Dr. Karl Schmidt, an American herpetologist at the Field Museum in Chicago, had been sent a live snake to identify by his colleague, Richard Marlin Perkins (then the director of the Lincoln Park Zoo).
