Answer

Answer

Projections, via the corticospinal tract and supplementary cortical areas (probably projecting onto spinal interneurons), and cortical inhibition of reticulospinal and rubrospinal systems, also influence spinal motor neuron set. Gamma efferent projections influence muscle spindle activity and therefore potentiate reflexes and spasticity.
