vogels_sprekeler_connection – Synapse type for symmetric spike-timing dependent plasticity with constant depression

Description

vogels_sprekeler_synapse is a connector to create synapses with symmetric spike time dependent plasticity and constant depression (as defined in 1). The learning rule is symmetric, i.e., the synapse is strengthened irrespective of the order of the pre- and postsynaptic spikes. Each pre-synaptic spike also causes a constant depression of the synaptic weight which differentiates this rule from other classical stdp rules.
