The posterior parietal cortex is a portion of the parietal lobe which manipulates mental images, and integrates sensory and motor portions of the brain.
Some sources say that it consists of Brodmann area 5 and Brodmann area 7.[1] Other sources say it is only area 7.[2]
Function
It is involved in formation of plans.[3]
There is evidence indicating that it plays a role in perception of pain.[4]
Recent findings have suggested that feelings of "free will" at least partially originate in this area.[5][6]
