Effect of tool: stick vs. laser. The stick > laser contrast revealed greater increases in activation in bilateral SPL, putative Brodmann Area 5, suggesting a remapping of reachable space or a distalization of the end-effector when pointing with a stick but not with a laser. No significant increases in activation were found for the reverse contrast, laser > stick. We examined differences between task conditions within the SPL ROIs identified by the stick > laser contrast in Fig. 8.
