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 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 can be changed in config_brian2_arbor_*.json or copied to a new configuration file, e.g., config_modified.json.

Then, call make like below for the modified configuration:

make comparison_modified.png

Or simply call

make

for the default configuration.

Requirements

• Brian2 >= 2.4.2
• Arbor >= 0.9.0
• matplotlib >= 3.4.1
• scipy >= 1.11.4
