The Sensible Brain: Adaptation as a Positive and as a Negative Factor in the Reorganization of Neuropsychological Systems After Brain Damage

  • Pierre Marie Lavorel
Part of the NATO Conference Series book series (NATOCS, volume 16)


In neuropsychology, adaptation is not a mechanism or an effect which has to be considered only occasionally. Adaptation is a permanent factor of behavior and of physical development or decay. Therefore, when neurophysiologists, neuropsychologists, and neurolinguists try to model their observations into brain theory or into cognitive theory, they always incorporate dynamic vectors. But difficulties arise when they have to define or decompose such general dynamic notions as adaptation into measurable, calculagle or predictable facts. An epistemological reflexion on how those scientists tackle their problems and what they discover about the most complex control systems known will perhaps suggest some analogous or homologous approaches in artificial intelligence, in engineering or even in social sciences like economics. To focus on one paradigm I have decided to insist here on some negative consequences of adaptation in aphasic behavior. But before dealing with the restructuring of cognitive processes used for language after brain damage, it is useful to recapitulate the concepts and the approaches, as well as the experimental knowledge and beliefs which have oriented neuropsychological research in recent years. For neurolinguistic theory has to relate linguistic research to advances in neurosciences.
