Figure 2.
The timeline of the experimental protocol. Each trial starts when the subject places their hand on the center button. Next, the auditory cue informs the subject which direction to reach. After a delayed period of more than 2 s, he releases his hands from the home position and reaches towards the target. In order to complete the movement, the subject returns back to the home position before starting the next trial. Only center-out reaching periods are considered. The average Tonset across all subjects in Experiment 1 is 5.03 ± 1.77 s.
