Prior Knowledge of Target Direction and Intended Movement Selection Improves Indirect Reaching Movement Decoding
Objective. Previous studies have demonstrated that target direction information presented by the dorsal premotor cortex (PMd) during movement planning could be incorporated into neural decoder for achieving better decoding performance. It is still unknown whether the neural decoder combined with only target direction could work in more complex tasks where obstacles impeded direct reaching paths...
متن کاملDecoding and cortical source localization for intended movement direction with MEG.
Magnetoencephalography (MEG) enables a noninvasive interface with the brain that is potentially capable of providing movement-related information similar to that obtained using more invasive neural recording techniques. Previous studies have shown that movement direction can be decoded from multichannel MEG signals recorded in humans performing wrist movements. We studied whether this informati...
متن کاملDistractor interference in selective reaching: effects of hemispace, movement direction, and type of movement.
In this study we investigated the influence of hemispace, movement direction, and type of movement on distractor interference in selective reaching. Participants reached for a green target while ignoring a simultaneously presented red distractor. In Experiment 1 participants performed rightward or leftward movements within the right or the left hemispace using their dominant (i.e., right) hand....
متن کاملCoupling between reaching movement direction and hand orientation for grasping.
In a previous work, we demonstrated that orientation of the hand in the horizontal plane (azimuth) at the time of grasping depends on the direction of the reaching movement in the horizontal plane. Here we report three experiments to further investigate the generality of this coupling. Azimuth of the hand for grasping was studied while subjects were reaching for objects placed at various locati...
متن کاملGoal-selection and movement-related conflict during bimanual reaching movements.
Conflict during bimanual movements can arise during the selection of movement goals or during movement planning and execution. We demonstrate a behavioral and neural dissociation of these 2 types of conflict. During functional magnetic resonance imaging scanning, participants performed bimanual reaching movements with symmetric (congruent) or orthogonal (incongruent) trajectories. The required ...
