# Command: stdp_synapse

NEST HelpDesk | Command Index | NEST Quick Reference

Name:

    stdp_synapse - Synapse type for spike-timing dependent
      plasticity.

Examples:

      multiplicative STDP [2]  mu_plus = mu_minus = 1.0
      additive STDP	 [3]  mu_plus = mu_minus = 0.0
      Guetig STDP	 [1]  mu_plus = mu_minus = [0.0,1.0]
      van Rossum STDP	 [4]  mu_plus = 0.0 mu_minus = 1.0

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   double	- Time constant of STDP window, potentiation in ms
      (tau_minus defined in post-synaptic neuron)
      lambda	 double	- Step size
      alpha	 double	- Asymmetry parameter (scales depressing increments as
      alpha*lambda)
      mu_plus   double	- Weight dependence exponent, potentiation
      mu_minus   double	- Weight dependence exponent, depression
      Wmax	 double	- Maximum allowed weight

Transmits:

    SpikeEvent
