vogels_sprekeler_synapse


Name:
vogels_sprekeler_synapse - 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 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.

Parameters:
 
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
[1])

Transmits:
SpikeEvent
