Grand averaged short-latency components of the SEP waveforms from each electrode. P20, N30, and P45 were measured by electrodes F3 and Fz (top panel), N18, P22, N30, and P45 by electrodes C3 and Cz (middle panel), and N20, P25, N33, and P45 by electrodes P3 and Pz (lower panel). Black lines are the grand averaged waveforms under nonimmersed control conditions from the 10 subjects. Grey lines are the grand averaged waveforms during water immersion.
