The human nervous system is structurally of inconceivable complexity. It is estimated that there are in the human brain about twelve thousand millions of nerve cells or neurons, and more than half of these are in the cerebral cortex. Were we to consider a million cortical nerve cells connected with one another in groups of only two neurons each and compute the possible combinations, we would find the number of possible interneuronic connection-patterns to be represented by ten to the power of two million, seven hundred, and eighty-three thousand. For comparison . . . probably the whole sidereal universe does not contain more than ten to the power of sixty-six atoms.
