What is it?

NMSAT is a Python package that provides a set of tools to build, simulate and analyse neuronal microcircuit models with any degree of complexity, as well as to probe the circuits with arbitrarily complex input stimuli / signals and to analyse the relevant functional aspects of single neuron, population and network dynamics. It provides a high-level wrapper for PyNEST (which is used as the core simulation engine). As such, the complexity of the microcircuits analysed and their building blocks (neuron and synapse models, circuit topology and connectivity, etc.), are determined by the models available in NEST. The use of NEST allows efficient and highly scalable simulations of very large and complex circuits, constrained only by the computational resources available to the user. The modular design allows the user to specify numerical experiments with varying degrees of complexity depending on concrete research objectives. The generality of some of these experiments allows the same types of measurements to be performed on a variety of different circuits, which can be useful for benchmarking and comparison purposes. Additionally, the code was designed to allow an effortless migration across computing systems, i.e. the same simulations can be executed in a local machine, in a computer cluster or a supercomputer, with straightforward resource allocation (see kernel parameters).

The code is licensed under GPLv2 and available on GitHub.

Disclaimer

The code was developed primarily for personal use, as part of a PhD project due to the need to perform similar experiments and analyses on very diverse systems. The goal was to use the same code to run different, but specialized, numerical experiments, in a fully transparent and reproducible manner, while making efficient use of computing resources. Due to the inherent time pressures of a PhD project and the broad scope, the code and documentation are under active use / development.
