ABSTRACT
The increasing survival rate of traumatically brain-injured (TBI) individuals has placed significant demands on rehabilitation professionals responsible for the accurate assessment and subsequent treatment needs of this population. The accurate assessment/evaluation of the individual with this single event, nonprogressive condition, has been viewed as having an increasingly important role in the development of rehabilitative strategies that maximize the return of independent functioning. Neuropsychology has traditionally focused on two major concerns: precise localization of brain lesions responsible for specific behavioral and medical disorders; and the analysis of brain-behavior relationships in an attempt to understand the brain as the principal organ of behavior. The traditional model of cerebral organization portrays a dichotomous brain with structural and functional differentiation between the right and left hemisphere. The integration of isomorphic and holistic theories of cerebral organization may be conceptualized utilizing the Functional Systems Theory.
