Introduction¶

This project will contain examples of the Izhikevich spiking neuron model.

Installation¶

Versions of the project¶

The original model in MATLAB format has been converted to a number of other formats.

PyNN¶

…

Tested with simulators: NEURON…

NeuroML 2¶

…

The XML for an Izhikevich model in NeuroML v2.0 is below:

<code class="xml">
<izhikevichCell id="TonicSpiking" v0 = "-70mV" thresh = "30mV" a ="0.02" b = "0.2" c = "-65.0" d = "6" Iamp="0" Idel="0ms" Idur="2000ms"/></code>

For full examples of single cells see TonicSpiking or PhasicBursting
