Actually, localization is true for the early phases of input systems (sensory) and for the later phases of output systems (motor). From the published paper:"This strongly suggests that PPC neurons encode choice-related signals related to decision formation or motor planning." 'Decision formation', if seen in isolation, sounds like a higher cognitive process; however, it is 'motor planning'. Here, one has enough freedom to fall back on the motor system and its dependence on the sensory system as well.
