Time-frequency analysis performed for channel 105 (marked in red on the grid schematic), separating the 4 movement directions and the trigger condition. Although there is a power inversion associated with movement, there is no clear separation between the movement conditions. Trials synchronized to joystick movement onset at 0 seconds.
