Brain areas showing significant decodings of planning grasp-to-use (GTU) and grasp-to-pass (GTP) tasks. A The demanding GTU (dGTU) and GTP tasks decoded for the right hand. B The dGTU and GTP tasks decoded for the left hand. C The easy GTU (eGTU) and GTP tasks decoded for the right hand. D The eGTU and GTP tasks decoded for the left hand. E–J The dGTU, GTP, and eGTU tasks decoded in the context of the reach-and-move (RAM) task, both for the right and left hand. Borders in panels A–D were displayed in areas where significant decoding accuracies were obtained. A constant set of parietal borders was used throughout panels E–J (except for cases with no decoding capabilities) as these borders correspond to the outcomes from the contrast involving planning reach-and-move action from the univariate analysis
