Time-frequency analysis performed for channel 113 (marked in green on the grid schematic), separating the 4 movement directions and the trigger condition. With this channel, the trigger condition separates clearly from the other conditions, with a marked increase in high-frequency power relative to the other 4 directional movement conditions. Trials synchronized to joystick movement onset at 0 seconds.
