A simple EEG electrode for intrauterine use in the

human fetus is described. The stainless steel screw

electrode possesses low noise characteristics, is

constructed from commercially available material, and is

easily attached to the fetal head during labor. Principles

of optical signal analysis as an improved method of

spectral analysis of the fetal EEG are also presented. The

optical system provides
