The legacy of association cortex.

C J Duffy

    Neurology
    |February 1, 1984
    PubMed
    Summary

    The association cortex, traditionally viewed through associationist and localizationist lenses, may instead be utilized by different functional systems dynamically. This challenges traditional interpretations and impacts understanding of cerebral neocortex lesions.

    Area of Science:

    • Neuroscience
    • Cognitive Science
    • Cerebral Cortex Research

    Background:

    • The concept of association cortex arose from historical associationist and localizationist theories of brain function.
    • Understanding of association cortex has been heavily influenced by these philosophical underpinnings.
    • Traditional views often linked specific functions to distinct cortical areas.

    Purpose of the Study:

    • To propose an alternative interpretation of association cortex function.
    • To challenge the traditional associationist and localizationist views.
    • To explore the implications of a distributed systems theory for understanding cerebral neocortex.

    Main Methods:

    • Conceptual analysis of historical and current theories of cortical function.
    • Integration of distributed systems theory with association cortex research.
    • Examination of the implications for neurological lesion studies.

    Main Results:

    • An alternative to the associationist interpretation suggests association cortex is utilized by different functional systems at different times.
    • This dynamic utilization aligns with the distributed systems theory of cortical function.
    • The findings have significant implications for how neurological lesions in the cerebral neocortex are understood.

    Conclusions:

    • The traditional associationist and localizationist views of association cortex may be incomplete.
    • A distributed systems perspective offers a more dynamic and flexible model of association cortex function.
    • This revised understanding is crucial for neurologists evaluating the impact of cerebral neocortex lesions.
