Fig. 7.

Subthreshold response properties of LFEM-1 and LFEM-2 in low-frequency bands with the different parameters of active ion channels. s soma, d dendrite. The normal parameters are set with g _Na = 30; g _KDR = 15; g _Ca = 10; g _KAHP = 0.8 and other parameters are set in “Appendix”. Only one parameter changes in every response curve. a Varying g _Na and g _KDR of somatic compartment; b varying g _Ca and g _KAHP of dendritic compartment; c varying the time-constants of KDR and KAHP channels i.e. τ _KDR and τ _KAHP. Note: the normal values of τ _KDR (2 ms) and τ _KAHP (1,000 ms) are achieved at the somatic resting state with about −10 mV
