Functional hemispheric asymmetries during the planning and manual control of virtual avatar movements

Description: Participants had to navigate a virtual avatar (cursor) on reference trajectories by means of isometric grip force. Reference trajectories varied according to spatial and temporal processing demands. They instructed either a virtual avatar movement with high spatial and high temporal processing demands (ST-condition), high spatial and low temporal processing demands (S-condition) or low spatial and high temporal processing demands (T-condition). The dataset contains second level contrast images of the planning and execution phase of the experiment. In addition it contains masks obtained from a model comparison approach to decide whether the response in a voxel was better predicted by regressors timed to planning or production.
