Dynamical Modeling of the Moth Pheromone-Sensitive Olfactory Receptor Neuron within Its Sensillar Environment
Figure 6
Effects of maximum conductance GMK on the response characteristics of RP at soma (RPs) and SP.
The repolarizing conductance GMK is the Ca2+- and voltage-dependent potassium conductance located at the inner dendrite and soma (the corresponding current IK is shown in Fig. 3). (A) The height of SP (solid lines) increases, while that of RPs (dashed lines) decreases with GMK respectively. (B) The ratio of amplitudes SP/RPs increases linearly with GMK at all uptakes. (C) The ratio of half-rising times of SP and RPs increases with GMK at low uptakes and becomes close to 1 at intermediate and high uptakes. (D) The ratio of the half-falling time of SP and RPs decreases with GMK at low uptakes and becomes close to 1 at intermediate and high uptakes. The vertical dotted lines indicate the reference value GMK = 1.6 nS given in Table 3.
