Name: clopath_synapse - Synapse type for voltage-based STDP after Clopath.
clopath_synapse is a connector to create Clopath synapses as defined in . In contrast to usual STDP, the change of the synaptic weight does not only depend on the pre- and postsynaptic spike timing but also on the postsynaptic membrane potential.
Clopath synapses require archiving of continuous quantities. Therefore Clopath synapses can only be connected to neuron models that are capable of doing this archiving. So far, compatible models are aeif_psc_delta_clopath and hh_psc_alpha_clopath.

Maximum allowed weight
Minimum allowed weight
Other parameters like the amplitudes for long-term potentiation (LTP) and depression (LTD) are stored in in the neuron models that are compatible with the Clopath synapse.
