This is the readme for the model associated with the paper: Moradi K, Moradi K, Ganjkhani M, Hajihasani M, Gharibzadeh S, Kaka G (2013) A fast model of voltage-dependent NMDA receptors J Comput Neurosci 34(3):521-531 This is the code that was used by the paper authors. A sample NMDA model from Exp01-Exp2NMDA-Fitting.hoc is loaded into the NEURON simulator in the auto-launch demo. 20140305 SynNMDA16.mod and SynNMDA16_2.mod were updated to work with a new version of NEURON (hg branch 1027) which also might fix potential initialization problems. The demo results are unchanged.
