The lecture on cell membrane potentials is a fundamental topic in physiology and biochemistry. The Hodgkin-Huxley model is a mathematical model that describes the ionic currents that flow across the membrane of a neuron. The model is based on the idea that the membrane potential is determined by the movement of ions, such as sodium and potassium, across the membrane.<br /><br />The change in membrane potential can be described by the following equation:<br /><br />$\Delta 4_{m}=4_{ar}-4_{in}$<br /><br />where $\Delta 4_{m}$ is the change in membrane potential, $4_{ar}$ is the resting membrane potential, and $4_{in}$ is the membrane potential at a given time.<br /><br />The gas equation, which describes the movement of ions across the membrane, is given by:<br /><br />$J=M_{0}+kTlnC+zF4$<br /><br />where $J$ is the flux of ions, $M_{0}$ is the initial concentration of ions, $k$ is the Boltzmann constant, $T$ is the temperature, $C$ is the concentration of ions, and $zF4$ is the charge of the ions.<br /><br />The Theorell equation, which describes the distribution of ions across the membrane, is given by:<br /><br />$\sum T_{m}=0$<br /><br />where $\sum T_{m}$ is the sum of the transmembrane potentials.<br /><br />The Nernst equation, which describes the relationship between the membrane potential and the concentration of ions, is given by:<br /><br />$M_{rest}=M_{11}-\sqrt {H_{24}}=0$<br /><br />where $M_{rest}$ is the resting membrane potential, $M_{11}$ is the concentration of ions at the membrane, and $H_{24}$ is the Henry constant.<br /><br />Overall, the lecture on cell membrane potentials provides a comprehensive understanding of the mechanisms that govern the movement of ions across the membrane and the resulting changes in membrane potential.
