Figure 3. Global increase of responses to odorants recorded by EOG in germfree animals.

Figure 3

(A,B) EOG responses to various odorants in conventional and germfree animals. Values represent the mean of peak amplitudes ± SEM (n = 12) (*P < 0.05; **P < 0.01; ***P < 0.001). (C) Average traces for 3 odorants from conventional (black) and germfree (red) animals. Small black line on top of recordings indicates odorant stimulation.
