Reflex Control of Fusimotor Neurones: Where do We Stand?
Studies on the central control of γ motoneurones have revealed a bewildering variety of fusimotor reflexes whose functional interpretation remains elusive. The bewilderment partly arises from our expectation that there should be simple schemes permitting convenient incorporation of straightforward notions of fusimotor reflex control into more complex schemes of higher order motor control. The final verdict may well be that the true organisation is much more complex than is convenient for simplifying didactic notions, or that the underlying organisation does not even lend itself to schematic simplification at all.
