stdp_synapse – Synapse type for spike-timing dependent plasticity

Description

stdp_synapse is a connector to create synapses with spike time dependent plasticity (as defined in 1). Here the weight dependence exponent can be set separately for potentiation and depression.

Parameters

tau_plus

ms

Time constant of STDP window, potentiation (tau_minus defined in postsynaptic neuron)

lambda

real

Step size

alpha

real

Asymmetry parameter (scales depressing increments as alpha*lambda)

mu_plus

real

Weight dependence exponent, potentiation

mu_minus

real

Weight dependence exponent, depression

Wmax

real

Maximum allowed weight

Transmits

SpikeEvent
