ModelDB: Working memory circuit with branched dendrites (Morita 2008)

Working memory circuit with branched dendrites (Morita 2008)

Accession: 117204

This is a rate-coding model of the neocortical spatial working memory circuit incorporating multiple dendritic branches of the individual pyramidal cell in order to examine how nonlinear dendritic integration, combined with the nonuniform distribution of the external input, affects the behavior of the whole circuit.

"SWMdend1.m" is a code for a single simulation trial of the circuit model.

It can be tested as follows: (as described in the top part of the
M-file itself)

[stim, x0, out, soas] = SWMdend1([100 100],[0 200 400],...
[pi/12 0 1],[pi/12 0 15],1.6,[pi/8 0 24 0.05],[0.1 5 0.1], ...
[pi/12 0.3 0.1 0.1],0.05,[]);

this creates figures that are similar to Fig 6B, for example:









"simulation_example.m" is a code for systematically running
"SWMdend1.m" for a large number of parameter sets.

"SWMdend1.m" includes codes for drawing figures, but they would be
problematic for a large scale simulation, because there will appear
too many figures.
