| Outline of Final Research Achievements |
Although humans can pursue a moving visual target overly and covertly, it is not clear yet whether the eye movements and attention share the common brain mechanisms or not. To answer such question, we measured MEG data during overt/covert pursuit tasks. We reconstructed the target trajectories from the estimated cortical currents using a sparse regression method. Test datasets demonstrated a good performance, and weight values were mainly distributed on precentral cortex, intraparietal cortex, and precuneus. These results indicated that these cortical areas play a common role for realizing overt/covert pursuit tasks to represent the spatial-temporal information of the target trajectories.
