A model of brain function: its implications for psychiatric research
BE Wexler
Much current research in psychiatry proceeds in the absence of an
integrated model of brain function. It is based instead on the effort to
relate clinical syndromes to single, localised abnormalities in the brain.
Such an approach is inconsistent with existing data, inadequate for linking
research findings with clinical practice, and, probably, fundamentally
misdirected. A model of brain function is presented that is based on
Luria's notion of cerebral functional systems and on the proposition that
the neural substrates of emotion are those processes that integrate
different brain regions. Some of the implications of this model for
research are discussed.
