Others, too, are interested in solving that mystery. Robert Galambos, 59, a professor of neurosciences at the University of California at San Diego, is at tempting to track auditory impulses from the ear, through the brain stem and into the cortex. He is studying several brain-wave patterns, including what is called the "Aha wave," which the brain generates when it finds what it is looking...
Subsequent experiments have proved that though the cortex is involved with memory, it does not act like a computer's memory bank, in which each bit of information is stored in a single electronic "cell." Memory, it has been found, is "delocalized" or spread throughout the cortex, and perhaps throughout the higher brain. Removing half the cortex may cause a proportional loss of capacity to remember, but it does not destroy specific memories...
...discovery of cortisone; in Rahway, N.J. After joining the Mayo Clinic in 1914, Kendall succeeded in isolating thyroxine from the thyroid glands of cattle, a development of importance to patients whose growth had been stunted by hormonal deficiencies. In 1930 he began research into the secretions of the adrenal cortex, and during eight years isolated six hormones, including cortisone, a substance effective in the treatment of rheumatoid arthritis, Addison's disease and other ailments...
Harvard's Richard Sidman, who was the first to apply the reassembly technique to brain cells, is now experimenting with a special variety of laboratory-produced mice called "reelers." A genetically caused "wiring" defect in the cerebellum and cerebral cortex of the reelers' brains impairs their coordination so completely that they stagger like drunks whenever they try to walk. Remarkably, when the brain tissue was taken from fetuses that had just developed the defect, Sidman's cells reorganized themselves in the same curious pattern...
Fine metal electrodes are placed in contact with brain cells in the visual cortex, and these record oscillographically the cell's discharge of nerve impulses in response to patterns of light projected on a screen viewed by the animals...
