stdp_pl_synapse_hom – Synapse type for spike-timing dependent plasticity with power law

Description

stdp_pl_synapse is a connector to create synapses with spike time dependent plasticity using homoegeneous parameters (as defined in 1).

Parameters

tau_plus	ms	Time constant of STDP window, potentiation (tau_minus defined in postsynaptic neuron)
lambda	real	Learning rate
alpha	real	Asymmetry parameter (scales depressing increments as alpha*lambda)
mu	real	Weight dependence exponent, potentiation

The parameters can only be set by SetDefaults and apply to all synapses of the model.

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.
