urbanczik_synapse – Synapse type for a plastic synapse after Urbanczik and Senn¶
Description¶
urbanczik_synapse
is a connector to create Urbanczik synapses as defined in
[1] that can connect suitable multicompartment models. In contrast to most STDP models, the synaptic weight
depends on the postsynaptic dendritic potential, in addition to the pre- and
postsynaptic spike timing.
Urbanczik synapses require the archiving of the dendritic membrane potential which is continuous in time. Therefore they can only be connected to neuron models that are capable of doing this archiving. So far, the only compatible model is pp_cond_exp_mc_urbanczik.
Warning
This synaptic plasticity rule does not take precise spike timing into account. When calculating the weight update, the precise spike time part of the timestamp is ignored.
Parameters¶
eta |
real |
Learning rate |
tau_Delta |
real |
Time constant of low pass filtering of the weight change |
Wmax |
real |
Maximum allowed weight |
Wmin |
real |
Minimum allowed weight |
All other parameters are stored in the neuron models that are compatible with the Urbanczik synapse.
