Science Frontiers ONLINE No. 13: Winter 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Half A Brain Sometimes Better Than A Whole One The orthodox view of the human brain holds that the left or dominant half governs the right side of the body and is concerned with logical thought, verbal analysis, etc. The right side of the brain controls the left side of the body and is responsible for spatial and intuitive thinking. The right side supposed-ly cannot even participate in verbal expression. The two halves of the brain are connected by the corpus callosum. That this interconnection sometimes creates problems is evident from the fact that its severance often leads to dramatic improvement in some types of epilepsy. These split-brain individuals, however, must contend with such bizarre situations as not being able to verbally identify objects seen or felt by the left eye and hand, even though they know what the objects are. Such situations merely confirm the orthodox view of the brain. But when half of the brain is completely removed, the conventional picture of the brain is upset. In one case, a woman with partial paralysis and frequent epileptic seizures had the left side of her brain removed. Her seizures and paralysis disappeared permanently; even more, her personality improved markedly. The half of the brain that remained assumed all brain functions and performed them better than the complete brain had. Conclusion: each half of the human brain has the intrinsic capability of operating as a whole brain despite the usual specialization of the halves. (Gooch, ...

... Science Frontiers ONLINE No. 137: SEP-OCT 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Phantom Bodies The phantom-limb phenomenon is well-known but poorly understood. A person who has lost a limb, or born without one, experiences pain, touch, heat, and many of the other normal sensations in the absent appendage. How can this be? Neuroscientist P. Brugger, at the University of Zurich, asserts the following: The brain contains a representation of the body, and disturbances in relevant neural networks by brain tumors or epilepsy can create the apparitions. Brugger means that the brain seems to have a neurological map of the entire body, even if a person is born without a leg or loses same in an accident. The phantom-limb phenomenon is thereby expanded to a "phantom-body" phenomenon. Continuing in this vein, tumors or those "neurological disturbances" could also produce the sensation of an entire phantom body. Could such whole-body apparitions be the source of the doppelgangers (images of one's self) that have been reported in the parapsychological literature and in folklore?

... Sourcebook Project Sourcebook Subjects Why most people are right-handed Depending upon which estimate you believe, 6 to 16% of us are left-handed. On the surface, left-handers seem little different from right-handers. So why the highly skewed population? Why not 50% of each? Dr. Peter Irwin, at Sanddoz, Ltd., of Basle, Switzerland, has what is certain to be a controversial answer. He was led to his conclusion by a series of experiments with psychoactive drugs, performed in collaboration with Professor Max Fink, SUNY, Stony Brook. Left-handers, the study demonstrated, are much more sensitive to drugs that act upon the central nervous system. Irwin believes that this finding is consistent with the known association of left-handedness with epilepsy and learning disorders. "But perhaps the most exciting aspect of Irwin's hypothesis is that it makes evolutionary sense. 'A greater resistance of right-handers to centrally active substances, when Man was a forager and before he learned to identify non-toxic edibles, would have favoured righthanded survival. This might account for the skew in the present handedness distribution that is unique to humans.'" And why should left-handers be more sensitive to psychoactive substances? Irwin thinks they must absorb or metabolize them differently, or perhaps there is a difference in the blood-brain barrier that affects the transport of substances into the brain. (Grist, Liz; "Why Most People Are Right-Handed," New Scientist, 22, August 16, 1984.) From ...
