by visual observation of the movements of the effector device. By assigning a new goal, the relationship among the recorded neurons is modified and the muscular movements previously elicited by the firing patterns of the neurons can disappear (e.g., Fetz, 2007; Nicolelis and Lebedev, 2009), an explicit demonstration that different readers (muscles vs actuators) gain control over the coordinated assembly activity of neurons. The success of BMI experiments demonstrates that arbitrarily chosen reader-actuator mechanisms (goals) can rapidly reshuffle assembly members and neural sentences can be composed with remarkable ease.
