Work toward real-time control of a cortical neural prothesis
... Neurons in the cerebral cortex typically display broad cosine tuning, and those in the motor cortex have been shown to be broadly tuned to the direction of hand movement [1]–[3]. These neurons will fire most rapidly for movements in their “preferred direction,” and least when the motion of the hand ...
