Questions related to the NEST simulator for large scale spiking neural network simulation with point neuron models. Questions should be relevant to StackOverflow and should be limited to the software aspects of the simulator, not neuroscience.
The NEST simulator is used for large scale spiking neural network simulations with point neuron models. It is one of the most prominent tools in the field of large scale network simulations. It has an SLI and Python interface.
The NEST simulator allows you to create populations of nodes - representing neurons - with a corresponding model and allows you to set parameters for that model on the individual nodes. For each timestep the membrane potential (the output) of each node is calculated based on the mathematical rules described by the model and the parameters set for the node. Nodes can be connected to eachother so that they can receive inputs based on the output value of other nodes.
