Does tool-related fMRI activity within the intraparietal sulcus reflect the plan to grasp?

Neuroimaging investigations reliably describe a left-lateralized network of areas as underlying the representations of knowledge about familiar tools. Among the critical 'nodes' of the network, an area centered within the left intraparietal sulcus (IPS) is thought to be related to the motoric representations associated with familiar tools and their usage. This area is in the vicinity of an area implicated in the control of object-directed grasping actions: the anterior intraparietal area, AIP.
