    • Populations
    • Cell property rules
    • Connectivity rules
    • Simulation configuration

  • Support for hybrid networks eg. combining point and multicompartment neurons.

  • Multiple connectivity functions (eg. full, convergent, probabilistic) with optional parameters (eg. delay range)

  • Support for user-defined connectivity functions.

  • Populations, cell properties and connectivity rules can include reference to annotations (eg. for provenance).

  • NEURON-specific instantiation of network ready for simulation.

  • Enables sharing of Python-based network objects, which can then be instantiated and simulated in NEURON.
