vogels_sprekeler_synapse - Synapse type for symmetric spike-timingDescription:
plasticity with constant depression.
vogels_sprekeler_synapse is a connector to create synapses with symmetric
spike time dependent plasticity and constant depression (as defined in ).
The learning rule is symmetric, i.e., the synapse is strengthened
irrespective of the order of the pre and post-synaptic spikes. Each
pre-synaptic spike also causes a constant depression of the synaptic weight
which differentiates this rule from other classical stdp rules.
tau double - Time constant of STDP window, potentiation in ms
Wmax double - Maximum allowed weight
eta double - learning rate
alpha double - constant depression (= 2 * tau * target firing rate in
