ten Tusscher Equations For Ion Channels

“m is an activation gate, h is a fast inactivation gate, and j is aslow inactivation gate. Each of these gates is governed by HodgkinHuxley-type equations.”

“x K1. is a time-independent inward rectification factor that is a function of voltage. Ko/5.4 represents the Ko dependence of the current.”
