The Neural Simulation Tool - NEST

NEST is a simulator for spiking neural network models that focuses on the dynamics, size and structure of neural systems rather than on the exact morphology of individual neurons.

A NEST simulation tries to follow the logic of an electrophysiological experiment that takes place inside a computer with the difference that the neural system to be investigated must be defined by the experimenter.

NEST is ideal for networks of spiking neurons of any size, for example:

• Models of information processing, e.g., in the visual or auditory cortex of mammals,
• Models of network activity dynamics, e.g., laminar cortical networks or balanced random networks,
• Models of learning and plasticity.

Key features of NEST

• NEST provides a Python interface or a stand-alone application
• NEST provides a large collection of neurons and synapse models
• NEST provides numerous example network scripts along with tutorials and guides to help you develop your simulation
• NEST has a large community of experienced developers and users; NEST was first released in 1994 under the name SYNOD, and has been extended and improved ever since
• NEST is extensible: you can extend NEST by adding your own modules
• NEST is scalable: Use NEST on your laptop or the largest supercomputers
• NEST is memory efficient: It makes the best use of your multi-core computer and compute clusters with minimal user intervention
• NEST is an open source project and is licensed under the GNU General Public License v2 or later
• NEST employs continuous integration workflows in order to maintain high code quality standards for correct and reproducible simulations

Installation

Quick Install

pip install nest-simulator

More details and options for installing NEST with pip can be found here:

https://nest-simulator.org/documentation/installation/pip_install.html

macOS Requirements

For macOS users, OpenMP support requires installing the OpenMP runtime library:

brew install libomp
pip install nest-simulator

This is necessary for NEST's multithreading capabilities to work correctly on macOS.
