To get started you should have a look at a few examples written with Auryn. The following simulations come with Auryn when downloaded and can be found in the
./examples folder under the Auryn root directory.
Starting from Auryn v0.7.0, examples are compiled automatically when building the simulator. See CompileAuryn to learn how to build Auryn and its examples using
cmake on diverse platforms.
Example code included with Auryn
The following examples can be found Auryn's /examples directory.
These are very simple models with a single neuron which can be easily understood and modified to get a first impression of how Auryn simulations are built.
- sim_poisson This example is Hello world in Auryn. It shows you how to create a simple PoissonGroup that fires at a given rate and writes the output to a ras file.
- sim_epsp Another rather simple simulation illustrating the recording of voltage or conductance traces from a single neuron.
- sim_epsp_stp A variation of the previous example, but using STPConnection which implements a synapse model with short term plasticity.
- sim_step_current Simulates step current input to a neuron (in this particular example to the Izhikevich model)
Here a few more common network simulation examples.
- sim_coba_benchmark The Vogels and Abbott network  in its 4000 neuron conductance based synapses version as used in [7,8].
- sim_isp_orig This simulation illustrates inhibitory plasticity in the Vogels and Abbott network. It is the parallelized version of our network used in Figure 4 in . (sim_isp_big An up-scaled version of this network to 200,000 neurons)
- sim_background A simulation implementing homeostatic triplet STDP at excitatory synapses. It was used in .
- sim_dense simulates a 25,000 neuron network with non-plastic connectivity of 10% which receives modulated external Poisson input. Similar to what we used in .
- sim_brunel2k and sim_brunel2k_pl Adapted from the Brunel balanced network  following the lines of  with and without STDP. We used these simulations for comparison with NEST in .

The code for these works can be found in separate repositories, but in some cases it might be closed too.
