Conductor.jl

Conductor.jl is a WIP. If the idea of a Julia-based neuronal network simulator engine sounds exciting to you, please feel free to reach out

Conductor.jl aims to be a platform for quickly and flexibly building high-performance, multi-scale neuronal network models in Julia. Under the hood it's being built on top of ModelingToolkit.jl--so all the tools available in the SciML and DiffEq ecosystem are (or soon will be) useable and composable with the neuronal models built here.

To install, tagged releases are available through the public registry:

# From Julia REPL
]add Conductor

While Conductor.jl is still in early development, you can get a feel for what's going on by looking in the demo directory of this repository. Clone the repository:

git clone https://github.com/wsphillips/Conductor.jl

Then from a Julia REPL:

cd("/path/to/Conductor.jl/demo")
using Pkg; Pkg.activate("."); Pkg.instantiate()

You should then be able to open and step through the various demo script examples.

Conductor.jl is based on the acausal component modeling paradigm in ModelingToolkit.jl. The initial draft of Conductor.jl was derived from an implementation of a stomatogastric ganglion (STG) model, which was written in Julia by Dhruva Raman, and based on published works by Astrid Prinz et al.

The original Julia/ModelingToolkit STG model template: NeuronBuilder.jl
