Some New Results On The Coding Of Pheromone Intensity In An Olfactory Sensory Neuron

A. Vermeulen, J.-P. Rospars, P. Lansky, H.C. Tuckwell

Abstract: Firstly, the effect of a neuron's spatial structure on the dependency of the receptor potential for a constant pheromone-dependent conductance is studied. It is shown that the ability to discriminate is improvced by considering a cable model instead of a point model neuron. Secondly, we compare the firing frequency when the passive backpropagation of action potentials is ignored [2,4] with the frequency when this backpropagation is included. For certain sets of parameters, the inclusion of backpropagation has little effect.
