An alpha synapse with time for rise equal to decay. A simple monoexponential synapse. A biexponential synapse. A synapse consisting of one rise and two decay time courses. A biexponential synapse exhibiting STD. A biexponential synapse with short term depression and facilitation. A biexponential blocking synapse, with STD. A biexponential blocking synapse with short term depression and facilitation. A single "synapse" which contains both AMPA and NMDA. It is planned that the need for extra synapse1Path/synapse2Path attributes can be removed in later versions.
