Fig. 12: Schematic illustration of the multicompartmental ORN model.
From: Stimulus duration encoding occurs early in the moth olfactory pathway
The model is composed of five different compartments: hemolymph, where the reference electrode is placed, auxiliary cells, sensillar lymph, dendrite, and soma. The difference of potential between the outer dendrite and the recording electrode (Ved) corresponds to the extracellularly measured signal.
