Dynamical Modeling of the Moth Pheromone-Sensitive Olfactory Receptor Neuron within Its Sensillar Environment
Figure 8
Outer-dendritic compartment and equivalent lumped conductance of the simplified model.
(A) Replacement of the original six-branch circuit including four pheromone-dependent conductances (gCa, gcat, gCl and gx as described in Fig. 1) with an equivalent three-branch circuit with a single pheromone-dependent conductance gpj given by eq. (21). (B) Kinetics of gpj in the first compartment (gp1) located at the tip of the outer dendrite in response to 2-s square pulses yielding different uptakes regularly spaces by 0.5 log units from 10−4.75 to 101.5 µM/s. (C) Idem in the 40th compartment at the base of the outer dendrite (gp40). Heights of the kinetics were taken at their maximum (indicated with double arrow in next to last uptake).
