[Analysis of geometric factors determining the parameters of an extracellularly recorded pyramidal neuron action potential].
Calculation of general extracellular field characteristics of a pyramidal neuron during generation of action potential included solution of the Laplas equation for extracellular field and Hodgkin--Huxley equations for electrotonic conduction along dendrites and for excitation of soma. The results were compared with available experimental data. The general factor for action potential amplitude near the soma seems to involve the distance from the soma rather than its size.
