Population firing rate trajectories. The thin faded lines show the z-scored population firing rate for the 1.5 seconds before and after the hand reached the target (vertical dashed line) for every trial across all testing days (6 for Subject 1, and 2 for Subject 2). The bold line shows the average z-scored population firing rate for each condition. Both subjects showed increased population firing before object contact, while neither showed increasing firing rates while reaching towards the empty target region.
