abstract：:Intentional action is essential to human behavior, yet its neural basis remains poorly understood. In order to identify neural networks specifically involved in intentional action, freely chosen and externally cued intentions have previously been contrasted. This has led to the identification of a fronto-parietal netw...

Sensorimotor mappings used in daily life range from direct or "standard" to highly complex. In "nonstandard" sensorimotor tasks, the visual stimulus guiding an action is often not the target ...
