Possible physical substrates for the interaction of electromagnetic fields with biologic membranes.

A quantized electrochemical model of a greater membrane concept that comprises the neuronal phospholipid sheet of the plasma membrane and the constituents of the intercellular spaces in brain tissue is proposed as a basis to explain several recent experimental results that concern the interaction of electromagnetic fields with the central nervous system. These fields consist of gradients far below those needed for direct intervention with action potentials or chemical transmitters at synaptic sites. Problems associated with the rectification of modulated signals and transduction into brain tissue are also briefly considered.
