Fig 1.
Schematic representation of electrode positions.
Left panel depicts electrode positions on the rump. R, Right Arm; L, Left Arm; F, Foot; Gnd, Ground. Right panel represents electrode positions on the head in the 10/20 system. Positions F0, Fz, O1, Oo and O2 were used (marked in red).
Fig 2.
The panel shows five body orientations from top view, side view in dry condition, and side view in immersed condition, consecutively.
