Olfactory Mitral Cell (Davison et al 2000)

Accession: 2487

A four-compartment model of a mammalian olfactory bulb mitral cell, reduced from the complex 286-compartment model described by Bhalla and Bower (1993). The compartments are soma/axon, secondary dendrites, primary dendrite shaft and primary dendrite tuft. The reduced model runs 75 or more times faster than the full model, making its use in large, realistic network models of the olfactory bulb practical.

Mitral cell model with four compartments

(soma/axon, secondary dendrites, primary dendrite shaft, primary
dendrite tuft)

      the mitral cell for use in network models of the olfactory bulb.

Run the model using the file mosinit.hoc after compiling the .mod files.

The graphs from fig. 6 in the paper can be reproduced by clicking the buttons
labelled "Stimulate soma with 0.2 uA/cm2" etc.:



A panel allows the parameters p, q, r, g_pg, g_sp, g_sd, alpha_s and alpha_g
to be varied.

Please note there are some typos in the paper:
(1) The current balance equation for Vd should be
	Cm Vd' = -Ileak - INa - IKfast + (gsd/s)(Vs-Vd)
    not
	Cm Vd' = -Ileak - INa - IKfast - (gsd/s)(Vs-Vd)

(2) In Table 1, g_pg should be 4.08 x 10^-4, not 4.08 x 10^-3
