The ion channels activation and inactivation variables in different membrane potentials. V s and V d are the somatic and dendritic membrane potentials from a reference potential of −60 mV a for soma and b for dendrite. m is Na + channel (I Na) activation gated variable; h is Na + channel (I Na) inactivation gated variable; n is K + channel (I KDR) activation gated variable; s is Ca 2+ channel (I Ca) activation gated variable; c is Ca 2+ activated K + (I KC) activation; q is K + AHP channel (I KAHP) activation gated variable
