Advanced Neurology MNS in patients with anxiety and depressive symptoms
Figure 1. Experimental design: The baseline data were recorded immediately before the new series of tasks. The subject sat opposite the demonstrator.
The first observation task started immediately after baseline, and the subject observed the demonstrator clenching their hand. The subject then performed
the movement (execution) and imagined themselves performing the movement (imagination). The last task was a joint execution—the subject and
demonstrator had to clench their hands synchronously while watching each other.
