Effects of HBO on the antidromic population spike (aPS). A: a 16-min exposure to 2.84 ATA O2 did not affect the amplitude of the aPS (n = 6). B: a 16-min exposure to 4.54 ATA O2 likewise did not significantly stimulate the amplitude of the aPS (n = 6). However, note the occurrence of secondary population spikes (sPS) during and following exposure to 4.54 ATA O2 (n = 3/6).
