Do central habituation and distraction alter C-fibre-mediated laser-evoked potential amplitudes?
In the approach of detecting C-fibre-mediated potentials with LEP, future studies should take the high susceptibility to distraction and habituation into account.
The results suggest that polymorphism in the promoter region of the OXT gene is most common in subjects with lactase non-persistence. This polymorphism may not be related to GI symptoms, as it is related to lactase non-persistence also in healthy controls.
