iaf_psc_alpha_multisynapse – Leaky integrate-and-fire neuron model with multiple ports ====================================================================================== Description +++++++++++ ``iaf_psc_alpha_multisynapse`` is a direct extension of ``iaf_psc_alpha``. On the postsynaptic side, there can be arbitrarily many synaptic time constants (``iaf_psc_alpha`` has exactly two: ``tau_syn_ex`` and ``tau_syn_in``). This can be reached by specifying separate receptor ports, each for a different time constant. The port number has to match the respective ``receptor_type`` in the connectors. .. note:: If ``tau_m`` is very close to ``tau_syn_ex`` or ``tau_syn_in``, the model will numerically behave as if ``tau_m`` is equal to ``tau_syn_ex`` or ``tau_syn_in``, respectively, to avoid numerical instabilities.
