Unformatted text preview: Outline of the Lecture Outline of the Lecture Hodgkin-Huxley Model Hodgkin-Huxley Model Membrane Currents Channels Gating Membrane Currents Channels Gating Mechanisms Mechanisms Voltage-dependent Gating Voltage-dependent Gating Mechanisms Mediate Mechanisms Mediate Action Potentials Action Potentials This circuits function depend on nonlinear synaptic mechanisms. Today, we will focus on models for action potentials. Equivalent-circuit models for action potentials are RC circuits with many conductances. c m d V d t = - + If A is the membrane surface area, c m is the capacitance per unit area, and i m is the sum of all membrane currents per unit area, then i m = - ( 29 + 4 - ( 29 + 3 - ( 29 Disregarding synapses (g s ), and making...
