Experimental setup. (1) The tACS and neuroimaging (EEG/fNIRS) setup is shown on a virtual subject. (2) The bimanual coordination task. In each trial, participants were instructed to operate the two joysticks (3) in order to direct a virtual dot on the screen as fast and as accurate as possible from the starting point (Δ) to the endpoint (graphic file with name fnbeh-12-00067-i002.jpg) of a predefined route. More details regarding the coordination task are in the text (paragraph Bimanual coordination task in section “Materials and Methods”).
