Document Summary

Non primary motor areas: prefrontal cortex as prepre motor cortex. Premotor cortex receives input from parietal cortex (what/how system) Posterior parietal cortex sends input to secondary motor cortex and prefrontal cortex. Areas that talk to each other can be close together (short, fast connections) Complicated networks provide a lot of exibility. More areas & more complicated wiring through primate evolution. Motor hierarchy: when you drive you need to follow the rules, you have rule structures. The prefrontal cortex is good at using rules and using the context of the situation to. Now if the light is green you have to press the accelerator and turn the wheel and look. So the premotor cortex is involved with sequencing. Motor learning: sensorimotor areas activated by performing a newly learned sequence of nger movements. Need more of prefrontal & parietal cortex & cerebellum at rst. As you learn, the areas activated are only the primary motor & somatosensory cortexes.
