Brian is a clock-driven simulator for spiking neural networks. It is designed with an emphasis on flexibility and extensibility, for rapid development and refinement of neural models. Neuron models are specified by sets of user-specified differential equations, threshold conditions and reset conditions (given as strings). The focus is primarily on networks of single compartment neuron models (e.g. leaky integrate-and-fire or Hodgkin-Huxley type neurons). Features include:
a system for specifying quantities with physical dimensions
exact numerical integration for linear differential equations
Euler, Runge-Kutta and exponential Euler integration for nonlinear differential equations
synaptic connections with delays
short-term and long-term plasticity (spike-timing dependent plasticity)
a library of standard model components, including integrate-and-fire equations, synapses and ionic currents
a toolbox for automatically fitting spiking neuron models to electrophysiological recordings
