Document Summary
Motor output is guided by sensory input. Learning can change the nature and the locus of sensorimotor control. Association cortex is at the top of your sensorimotor hierarchy. There are two major areas of sensorimotor association cortex: the posterior parietal association cortex, the dorsolateral prefrontal association cortex. The posterior parietal association cortex plays an important tole in integrating these two kinds of information, in directing behaviour by providing spatial information, and in directing attention. The posterior parietal cortex is an association cortex because it receives information from the three sensory systems that play roles in the localization of the body and external objects in space: visual system, auditory system, somatosensory system. Much of the outout of the ppc goes to areas of motor cortex located in the frontal cortex: dorsolateral prefrontal association cortex, secondary motor cortex, frontal eye field.
