Excitation of the Nervous Membrane Hodgkin-Huxley Equations

4 Excitation of the Nervous Membrane Hodgkin-Huxley Equations 

The nervous membrane is the wall of the nervous cell. Its excitation is the basic process of the propagation of information along the axons, which are the conduction elements of the nervous cell. The essential variables of the excitation process are 

These voltage peaks or action potentials travel along the axon and carry the information with them. The intensity of information is coded as the frequency or firing rate of the attion potentials. This frequency usually varies between 5 and 100 Hz maximum frequencies have been observed up to 1,000 Hz. This implies a time interval of a few microseconds for the single action potentials. 

The basis of the Hodgkin-Huxley descriptive model is the qualitative resemblance of the resting potential V = V -60 mV between the excitation peaks and of the peak voltage V = Vp +50 mV with the Nernst potentials of K and Na across the nervous membrane  

K and Na , respectively, and F is Faraday s constant. The voltage values given in
