24The exact mechanisms by which humans control the manual interception of moving targets 25 are currently unknown. Here, we explored the behaviours associated with the spatial 26 control for manual interception. The examined task required controlling a cursor to 27 intercept moving targets on a touch screen. We explored the effects of target motion 28 direction, curvature and occlusion on manual interception. We observed occlusion-
Catching movements must be aimed ahead of the moving ball, which may require predictions of when and where to catch. Here, using repetitive Transcranial Magnetic Stimulation we show for the first time that the Superior Parietal Occipital Cortex (SPOC) displays non-predictive online spatial coding at the moment the interception movements were already aimed at the predicted final target position. The ability to aim ahead for catching must thus arise downstream within the parietofrontal network for reaching.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
