Abstract

A simple calculation of the current dipole moment of the extracellular electric field of the cortex is proposed; it is based on the dipole layer model. The model is extended to the range of microwave frequencies. Arguments in favor of emission of microwave radiation by the dendritic membranes of pyramidal neurons are presented and the strength of the radiative electric field at a distance from the head is calculated and discussed.

Main findings

A dipole layer model is used to calculate the current dipole moment of the cortical extracellular electric field and is extended to microwave frequencies. The paper presents arguments for possible microwave radiation emission by dendritic membranes of pyramidal neurons and calculates/discusses the radiative electric field strength at a distance from the head.
