Split Brain Research Roger Sperry Betty Edwards
“ The two disconnected hemispheres function independently and in effect have each a separate mind of its own. Each of the separated hemispheres appears to have its own private sensations, perceptions, thoughts, feelings and memories. Each hemisphere has its own inner visual world, each cut off from the conscious awareness of the other.” ~Roger Sperry
Left-hemisphere (L-mode): foursquare, upright, sensible, direct, true, hard-edged, un-fanciful, and forceful Right- hemisphere (R-mode): curvy, flexible, more playful in its unexpected twists and turns, more complex, diagonal, and fanciful Are you Right or Left Brained?

“ For some tasks, responses concentrate heavily in one hemisphere while for other cognitive functions both hemispheres respond robustly. In many studies, responses fall between these two extremes. Even the ability to read and write in English – where a strong left hemisphere response is well documented – involves right hemisphere activity.” ~ Irene Schiferl
“ How can you expect to talk about realism, perspective and other sights of the eye if you don’t actually know how the eyes and brain work?” ~Irene Schiferl
