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. Proudly powered by WordPress “The objective psychologist, hoping to get at the physiological side of behavior, is apt to plunge immediately into neurology trying to correlate brain activity with modes of experience … The result in many cases only accentuates the gap between the total experience as studied by the psychologist and neural activity as analyzed by the neurologist.” In Sperry and Gazzaniga's "The Split Brain in Man" experiment published in Scientific American in 1967 they attempted to explore the extent to which two halves of the human brain were able to function independently and whether or not they had separate and unique abilities. 5- 19.

He found that if hemispheres were not connected, they functioned independently of one another, which he called a split-brain. Depending on which eye was covered, the cats would either distinguish a square from a triangle or a triangle from a square, demonstrating that the left and right hemispheres learned and remembered two different events. A logical development from Sperry and Geschwind's studies is BOLD fMRI technology that demonstrates regional time-varying changes in brain metabolism – a more precise method of exploring brain networks.
