Accession:2730
A biologically-detailed model of the mammalian olfactory bulb, incorporating the mitral and granule cells and the dendrodendritic synapses between them. The results of simulation experiments with electrical stimulation agree closely in most details with published experimental data. The model predicts that the time course of dendrodendritic inhibition is dependent on the network connectivity as well as on the intrinsic parameters of the synapses. In response to simulated odor stimulation, strongly activated mitral cells tend to suppress neighboring cells, the mitral cells readily synchronize their firing, and increasing the stimulus intensity increases the degree of synchronization. For more details, see the reference below.

# gnuplot file to produce a figure similar to Figure 8
# in Davison A.P., Feng J. and Brown D. (2003) J. Neurophysiol.

# Note that the figure produced will not match exactly the
# published figure due to differences in the sequence of
# random numbers used to set up the network.
