Distribution of butanol molecules along bullfrog olfactory mucosa

Abstract

ALTHOUGH electrophysiological¹ and gas chromatographic² studies have indicated that odorant molecules drawn into the intact frog olfactory sac establish a concentration gradient along the olfactory mucosa, conclusive evidence for such gradients requires a direct determination of how the molecules are actually distributed. This requirement is met here by labelling butanol molecules with tritium and directly mapping their sorption along the mucosa.
