CHAPTER 2: DISCOVERING A MIND DIVIDED
Video 1: https://vimeo.com/96626442
Early documentary on split-brain work where I was asked to describe how we tested the early split-brain patients. Believe it or not, I was old enough to shave. The experimental set-up at the time of this filming was a step up from the original back-projection screen that was hanging from an exposed pipe in one of the lab rooms in Alles Hall.
Video 2: https://vimeo.com/96626444
Case N.G. swimming not long after her surgery and demonstrating the full callosal sectioning seemingly did not disrupt basic bilateral coordination in any way. In short, the untrained observer would be hard-pressed to detect that the two halves of the brain had been surgically separated.
Video 3: https://vimeo.com/96626445
The original film was shot by Baron Wolman a talented young photographer and one of the founders of Rolling Stone magazine. It shows Case W.J. easily putting together four colored blocks with his left hand to match a sample picture provided to him. His left hand gained its major control from the right hemisphere. When the dominant right hand tried, he simply failed. When both were free to try, one seemed to undue the accomplishments of the other.
CHAPTER 3: SEARCHING FOR THE BRAIN’S MORSE CODE
Video 4: https://vimeo.com/96626446
Case D.R. A patient from the East Coast series of cases carrying out command to posture either her left or right hand. Watch a few times and you will begin to see how she uses self-cueing strategies to achieve her goal.
Video 5: https://vimeo.com/96626447
Case N.G. is presented words and pictures exclusively to her right hemisphere. She cannot name them, even though her left hand is able to find the correct object.
Video 6: https://vimeo.com/96627695}
Emotional states spread throughout the brain rapidly. Here Case N.G. was shown evocative nude photos to the right hemisphere. While her left hemisphere couldn’t say what the picture had been, it could recognize something funny had happened.
CHAPTER 4: UNMASKING MORE MODULES
Video 7: https://vimeo.com/96627698
Filmed in our original trailer set-up, we would lateralize questions to the right hemisphere by first saying “Who is your favorite____?” and then lateralize the last part of the question to either the right or left hemisphere. Here we asked the right hemisphere “Who is your favorite girlfriend?” Since he was a patient that could control both hands from one hemisphere, both cooperated in arranging Scrabble letters to spell “LIZ.”
Video 8: https://vimeo.com/96627699
We examined Case P.S.’s right hemisphere on many dimensions. Here we ask “Who are you?” The right hemisphere answers “Paul.”
Video 9: https://vimeo.com/96627700
Case P.S.’s right hemisphere tells us about his favorite TV show and Henry Winkler.
Video 10: https://vimeo.com/96627702
Case J.W. working on a simple experiment a few years later and filmed by Robert Bazell at NBC News. It was “live” science and it all worked.
CHAPTER 6: STILL SPLIT
Video 11: https://vimeo.com/96628407
A double grid with each hemisphere seeing one grid of nine cells. Lights would appear randomly, four at a time, in each field—an overwhelming experience for normal subjects. Split-brain patients could manage the task with ease.
Video 12: https://vimeo.com/96628410
J.W. being examined by me in our GMC Eleganza van. The word “sun” had been flashed to left brain and a black-and-white line drawing of a traffic light to his right brain. Teaching him how to play Twenty Questions also taught him how to gain access to the right-brain information from the left brain.
Video 13: https://vimeo.com/96628408
Case J.W. being instructed to smile from the left hemisphere. Watch the asymmetrical retraction of his face muscles on right side of his face, followed by the left-side response. Also notice the asymmetry as the face starts to regain the neutral posture.
CHAPTER 7: THE RIGHT BRAIN HAS SOMETHING TO SAY
Video 14: https://vimeo.com/96628409
Jim Eliassen’s task where J.W. is able to do two things at once whereas most of us cannot.
