The spontaneous electroencephalogram (EEG) and the visual evoked cortical electrical activity (visual evoked response, VER) were studied in young adult males to ascertain the effects of exposure to carbon monoxide (CO). The EEG was found to be generally resistant to change during eight hours of exposure at the lower CO concentrations (maximum carboxyhemoglobin saturations of 10 and 22 percent). During the eight hour exposures, the VER was generally resistant to change until COHb levels of 22 percent were achieved, while with 24 hours of exposure changes were evident even at the lowest concentrations (COHb equals 4-10 percent). This change, an increase in VER wave amplitude, suggest that these exposures induced central nervous system depression.
