Abstract Conventional metal electrodes can
cause serious modification and intensification of the rate of energy
absorption in tissues during exposure of animals to microwaves. Carbon-loaded
Teflon with a conductivity close to that of tissue
has been implanted and maintained for four to six months at cortical and subcortical locations in rabbits. The EEG and its
spectrum as recorded from the carbon-loaded Teflon electrodes are comparable
to those recorded from conventional metal electrodes. Histological
examination showed good tissue compatibility, Recordings made during acute
exposure of rabbits to microwave radiation (2450-MHz) at
100 mW/cm² showed no electromagnetic interference. The results
indicate that carbon-loaded Teflon electrodes can be implanted chronically to
record the EEG in animals during the course of microwave radiation. |
