| 概要 | Izhikevich artificial neuron model from EM Izhikevich "Simple Model of Spiking Neurons" IEEE Transactions On Neural Networks, Vol. 14, No. 6, November 2003 pp 1569-1572 Files: izh.m // Matlab program to replicate firing patterns izh.gif // illustration of firing patterns izh.mod // Neuron mod file to replicate firing patterns (note limitations below) izh.hoc // Neuron hoc file Usage : matlab izh.m OR nrnivmodl izh nrngui izh.hoc solves the following equations: v' = e*v^2 + f*v + g - u + I; RESET if (v>30) v=c u' = a*(b*v-u); RESET if (v>30) u=u+d (note that vv is used in Neuron for voltage so doesn't interfere with built-in v of cell) a,b,c,d,I are the major parameters; f,g are reset for 2 simulations (G-"Class 1" and L-"integrator") all parameters can be controlled from parameter panel 3 of the simulations shown in izh.gif are not properly replicated: Q: depolarizing afterpotential does not repolarize properly R: accomodation requires an alteration of the functional forms to replicate (alternate functional form given on line 52 of izh.mod) T: too unstable for Neuron integrators to handle (changing izh.hoc line 203 to Isend1(50,75) will crash simulator) izhstim() // sets up a single NetStim input at 1 ms into the Izhikevich cell [izh.hoc42 izh.mod16] |
