The primate premotor cortex: past, present, and preparatory.

S P Wise

    Annual Review of Neuroscience
    |January 1, 1985

    Summary

    The premotor cortex, once disregarded, is now recognized as a key motor control area. Research suggests its role in movement preparation and sensory guidance.

    Area of Science:

    • Neuroscience
    • Motor Control
    • Cerebral Cortex Function

    Background:

    • The concept of a distinct premotor cortical field for movement control faced decline between 1952 and 1977.
    • Recent neurophysiological studies have prompted a re-evaluation and rehabilitation of this concept.

    Purpose of the Study:

    • To explore the current understanding and functional specialization of the premotor cortex.
    • To assess the evidence supporting various hypotheses regarding premotor cortex function.

    Main Methods:

    • Review of recent neurophysiological studies and existing literature.
    • Analysis of proposals concerning the functional specializations of different motor cortical fields.

    Main Results:

    • The premotor cortex is identified as one of at least three fields within the motor cortex, alongside the primary motor cortex and supplementary motor cortex.
    • Current evidence, while not definitive, best supports a role for the premotor cortex in movement preparation.

    Conclusions:

    • The premotor cortex has been rehabilitated as a significant area in motor control research.
    • The strongest evidence indicates the premotor cortex is involved in the sensory guidance of movement.
