Trial-by-Trial Adaptation of Movements during Mental Practice under Force Field
Figure 1
Experimental setup and trial protocol.
(a) Robotic manipulandum system was used to deliver required perturbations during the course of reaching movement. A setup for 2D movements was used to record the trajectories followed by different subjects under the application of external force field. This movement onset was controlled through a feedback mechanism involving EEG
(b) Eight possible motion directions are shown. All paths are spaced at regular intervals of . Anticlockwise force field was turned on/off during the experiment
(c) Timeline for each trial is shown. Total duration is subdivided into several intervals bounded by commands issued by the controller
