To touch or not to touch: posterior parietal cortex and voluntary behavior.
The primate posterior parietal cortex has been implicated in a large number of cognitive functions. In this issue of Neuron, Cui and Andersen show that neurons in this area maintain effector-specific coding of motor intentions without specific sensory instructions and therefore when behavior is chosen by the animal freely.
