STDP

Spike-driven plasticity

A synapse with spike-timing-dependent plasticity (STDP) has been added to Arbor.

The implementation is validated against the Brian 2 and the NEST simulator.

How to

First, install Arbor. If you install from source, make sure arbor-build-catalogue from the Arbor scripts directory is in PATH, or modify the Makefile accordingly.

Next, if necessary, adapt run_arbor.sh and run_brian2.sh to your environment.

Parameters for the provided simulations ("LIF" and "classical") can be changed in config_lif,json or config_classical.json.

Then, use the make calls below for the comparison between Arbor and Brian 2 or NEST:

make make comparison_brian2_arbor.png
make make comparison_nest_arbor.png

Or simply call

make

for the default configuration (Arbor and Brian 2).

Requirements

• Brian2 >= 2.4.2
• NEST >= 3.8.0
• Arbor >= 0.9.0
• matplotlib >= 3.4.1
• scipy >= 1.11.4
• scikit-learn >= 1.5.0
