  • Comments: TITLE Voltage-gated potassium channel from Kv3 subunits COMMENT Voltage-gated potassium channel with high threshold and fast activation/deactivation kinetics KINETIC SCHEME: Hodgkin-Huxley (n^4) n'= alpha * (1-n) - betha * n g(v) = gbar * n^4 * ( v-ek ) The rate constants of activation (alpha) and deactivation (beta) were approximated by: alpha(v) = ca * exp(-(v+cva)/cka) beta(v) = cb * exp(-(v+cvb)/ckb) Parameters can, cvan, ckan, cbn, cvbn, ckbn are given in the CONSTANT block. Values derive from least-square fits to experimental data of G/Gmax(v) and taun(v) in Martina et al. J Neurophys. 97 (563-671, 2007. Model includes a calculation of Kv gating current Reference: Akemann et al., Biophys. J.
