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.
