Right brain goes to Heaven, Left brain goes to Hell!
One unusual feature of the brain is that it has two nearly identical halves, or hemispheres, the left and right. Scientists have long wondered why the brain has this unnecessary redundancy, since the brain can operate even if one entire hemisphere is completely removed. Furthermore, if each hemisphere has consciousness, does this mean that we have two separate centers of consciousness inside one skull?
Dr. Roger W. Sperry of the California Institute of Technology won the Nobel Prize in 1981 for showing that the two hemispheres of the brain are not exact carbon copies of each other, but actually perform different duties.
Dr. Roger was treating epileptics, who sometimes suffer from Grand mal seizures often caused by feedback loops between the two hemispheres that go out of control. He began by severing the Corpus Callosum, which connects the two hemispheres of the brain, so that they no longer communicated and shared information between the left and right side of the body. This usually stopped the feedback loop and the seizures.
Normally the hemispheres complement each other as thoughts move back and forth between the two. The left brain is more analytical and logical. It is where verbal skills are found, while the right brain is more holistic and artistic. But the left brain is the dominant one and makes the final decisions. Commands pass from the left brain to the right brain via the corpus callosum. But if that connection is cut, it means that the right brain is now free from the dictatorship of the left brain. Perhaps the right brain can have a will of its own, contradicting the wishes of the dominant left brain.
In short, there could be two wills acting within one skull, sometimes struggling for control of the body. This creates the bizarre situation where the left hand (controlled by the right brain) starts to behave independently of your wishes, as if it were an alien appendage.
There is one documented case in which a man was about to hug his wife with one hand, only to find that the other hand had an entirely different agenda. It delivered a right hook to her face. Another woman reported that she would pick out a dress with one hand, only to see her other hand grab an entirely different outfit. Meanwhile, one man had difficulty sleeping at night thinking that his other rebellious hand might strangle him.
Dr. Roger, after detailed studies of split-brain patients, finally concluded that there could be two distinct minds operating in a single brain. He wrote that each hemisphere is “indeed a conscious system in its own right, perceiving, thinking, remembering, reasoning, willing, and emoting, all at a characteristically human level, and?…?both the left and right hemisphere may be conscious simultaneously in different, even in mutually conflicting, mental experiences that run along in parallel.”
There are a variety of ways to communicate separately to each hemisphere without the knowledge of the other hemisphere. One can, for example, have the subject wear special glasses on which questions can be shown to each eye separately, so that directing questions to each hemisphere is easy. The hard part is trying to get an answer from each hemisphere. Since the right brain cannot speak (the speech centers are located only in the left brain), it is difficult to get answers from the right brain. To find out what the right brain was thinking, Dr. Gazzaniga created an experiment in which the (mute) right brain could “talk” by using Scrabble letters.
He began by asking the patient’s left brain what he would do after graduation. The patient replied that he wanted to become a draftsman. But things got interesting when the (mute) right brain was asked the same question. The right brain spelled out the words: “automobile racer.” Unknown to the dominant left brain, the right brain secretly had a completely different agenda for the future. The right brain literally had a mind of its own.
Perhaps there is truth to the oft-heard statement that “inside him, there is someone yearning to be free.” This means that the two hemispheres may even have different beliefs. For example, the neurologist V. S. Ramanchandran describes one split-brain patient who, when asked if he was a believer or not, said he was an atheist, but his right brain declared he was a believer. Apparently, it is possible to have two opposing religious beliefs residing in the same brain. Ramachandran continues: “If that person dies, what happens? Does one hemisphere go to heaven and the other go to hell? I don’t know the answer to that.”
