Human memory, formerly believed to be rather inefficient, is really more sophisticated
than that of a computer. Researchers approaching the problem from a variety of view
points have all concluded that there is a great deal more stored in our minds than has been
generally supposed. Dr. Wilder Penfield, a Canadian neurosurgeon, proved that by
stimulating their brains electrically, he could elicit the total recall of specific events in his
subjects’ lives. Even dreams and other minor events supposedly forgotten for many years
suddenly emerged in detail.
Although the physical basic for memory is not yet understood, one theory is that the
fantastic capacity for storage in the brain is the result of an almost unlimited combination
of interconnections between brain cells, stimulated by patterns of activity. Repeated
references to the same information support recall. Or to say that another way, improved
performance is the result of strengthening the chemical bonds in the memory.
