Predicted BOLD signal changes based on our four contrasts during the delay phase for the voxelwise group data. A, We expected that areas involved in reach target representation for Egocentric (Ego) and Allocentric (Allo) reach tasks would elicit higher activation compared with the Color report (Color) task. B, Areas involved in coding reach target in egocentric coordinates would elicit higher activation in the Ego task as opposed to the Allo task and vice versa. We did not have any specific prediction about the level of activation in the Color task compared with the Allo task for allocentric coding areas. C, We expected that egocentric directional selectivity (target location relative to gaze) would be revealed by higher activation for target to the right versus left of the gaze in the left hemisphere. D, We expected that allocentric directional selectivity (target location relative to landmark location) would be revealed by higher activation for target to the right versus left of the landmark in the left hemisphere.
