Example of a successful trial. Note. Example of a successful trial using only acoustic stimulation is presented. In Panel A, the displacement of the index finger (red line), the thumb (blue line), and the average trajectory (black line), in the x–y coordinates. Panel B illustrates the temporal evolution of the distance between index finger and thumb during the trial. The onset of grasping and the maximum hand aperture were highlighted with red dots. Moreover, the onset of the was used to split the reaching from the grasping phase
