Recent research has now recognized and clarified the cerebellum s influence and functions. Fundamentally involved in producing handwriting, it regulates and coordinates smooth movement. The cerebellum has a far greater influence in higher brain functions that was previously recognized. Its subtle influence is seen in carrying out willed acts and control of hostile impulses. Repetitive movement also enhances myelination of the axons, long neural fibers that transmits messages from the neural cell body to the synaptic gap at the end of the dendrites.
Myelin insulates the axon fiber, much as the copper wire in an electrical cord is insulated.
More importantly, sufficiently developed myelinated neural networks are protected from a chemical housecleaning which nature releases around age 11. This action dissolves all undeveloped neural fields leaving the brain with the weight it had at 18 months. Not having to produce cognitive results removes stress and anxiety in trying to meet expectations. Visual, auditory and kinesthetic stimulation creates a powerful synergy that is more effective than either component alone. Poor handwriting indicates a child is under stress and is emotionally vulnerable.
