Early investigations of internal functioning in the brain tended to suggest considerable randomness—say in the sequence of electrical pulses from a nerve cell. But in recent years, with more extensive measurement methods, there has been increasing evidence for precise deterministic underlying rules. (See pages 976 and 1011.)
