Document Summary
The nervous system can use both the visual and kinaesthetic systems within around 200 milliseconds: when you have both senses available, then you use some combination of both of them. Kinaesthesia is used more for tasks that need ne motor control, like writing, handwriting, and piano. Vision is used for movements to targets outside of your space, like reaching for something. After information goes past the optic chiasm, some of the axons goto the superior colliculus, and others goto the visual cortex. At the visual cortex the information splits again to ventral and dorsal. Ventral stream is for recognition, and dorsal stream is for action. How do we produce voluntary movement: you develop abstract motor plans within your brain that represent the intended movements you want to make. There are 2 major pathways through the spinal cord, lateral and ventromedial pathways.
