NEURON { POINT_PROCESS AMPA } : GLUTAMATE SYNAPSE (AMPA-Kainate receptors) : : Parameters estimated from whole cell recordings of synaptic currents on : Cochlear neurons (Raman & Trussel, Neuron 9: 173-186, 1992) as well as : from sharp electrode EPSP's recordings in thalamocortical neurons (LGN) : (Crunelli et al. J. Physiol. 384: 603, 1987). PARAMETER { Cmax = 1 (mM) : max transmitter concentration Cdur = 1.1 (ms) : transmitter duration (rising phase) Alpha = 10 (/ms mM) : forward (binding) rate Beta = 0.5 (/ms) : backward (unbinding) rate Erev = 0 (mV) : reversal potential Prethresh = 0 : voltage level nec for release Deadtime = 2.5 (ms) : mimimum time between release events gmax (umho) : maximum conductance } INCLUDE "synq.inc" :________________________________________________________________
