Example of a SR response with a completed APA-reach sequence as shown by anterior displacement of hand (top window), posterior center of pressure (CoP) displacement (2nd window), and corresponding muscle activation (3rd–5th windows) after the LAS before the go cue and b absent response with neither SR response in APA nor SR response in reach. Blue vertical lines represent the timing of the warning cue. Red vertical lines represent the timing of the LAS. Green lines represent the timing of the go cue. Note that the LAS is at − 200 ms relative to the go cue
