THE BASIC THESIS OF THE AUTHOR IS THAT THE NERVOUS SYSTEM OF MAN HAS EVOLVED FROM A VERY SIMPLE TO A VERY COMPLEX MECHANISM. MAN HAS ACHIEVED CORTICAL DOMINANCE WHEREIN ONE SIDE OF THE CORTEX CONTROLS THE SKILLS WHICH SEPARATE MAN FROM OTHER ANIMALS. THIS EVOLUTIONARY PROCESS MUST BE RECAPITULATED ONTOGENETICALLY OR MOBILITY AND COMMUNICATION DIFFICULTIES APPEAR. TO REMEDY THE SITUATION, THOSE AREAS OF NEUROLOGICAL ORGANIZATION THAT ARE INCOMPLETE OR ABSENT MUST BE TAUGHT TO OR IMPOSED ON THE NERVOUS SYSTEM THROUGH ADEQUATE PRACTICE AT THE VARIOUS LEVELS OF CORTICAL DEVELOPMENT. THE AUTHOR DISCUSSES THE PHYLOGENY AND ONTOGENY OF NEUROLOGICAL DEVELOPMENT. HE RELATES NEUROLOGICAL ORGANIZATION TO BRAIN INJURY AND PRESENTS SEVERAL DIAGNOSTIC AND TREATMENT PROCEDURES FOR SPEECH AND READING PROBLEMS. A 95-ITEM BIBLIOGRAPHY IS INCLUDED.
