Detailed Description

Base Class for Glutamate synapse with NMDA and AMPA channels.

This is a slow version of a glutamate-synapse. NMDA and AMPA channels are conductance based Attention: Neuron needs biological resting potential (ca. -70mV). Note that this synapse can not be used as an inhibitory synapse! Since channels are conductance based, weight has to be much larger (about 50x)

Public Attributes

  • float tau_nmda
    The NMDA time constant $\tau_{nmda}$ [units=sec; range=(0,100)];.
  • float Mg_conc
    Mg-concentration for voltage-dependence of NMDA-channel in [units=mMol].
  • float E_nmda
    Reversal Potential for NMDA-Receptors [units=V].
  • float E_ampa
    Reversal Potential for AMPA-Receptors [units=V].
  • float fact_nmda
    The impact of NMDA-type channels is a fraction of the impact of the normal (AMPA) channels. This variable is multiplied to the weight to get the NMDA-impact.
  • float fact_ampa
    The impact of NMDA-type channels is a fraction of the impact of the normal (AMPA) channels. This variable is multiplied to the weight to get the AMPA-impact.
  • double psr_nmda
    The psr (postsynaptic response) for nmda channels.

float GlutamateSynapse::tau_nmda
 

The NMDA time constant $\tau_{nmda}$ [units=sec; range=(0,100)];.

A spike causes a exponential decaying postsynaptic response of the form $\exp(-t/\tau_{nmda})$
