Abstract : Two series of experiments were carried out to investigate the relationship between the depression of the cortical evoked response and inert gas narcosis. In the first series mental arithmetic performance and the auditory evoked response (AER) were measured while breathing air and a 20-80% oxy-argon mixture at 4 and 7 ATA (atmospheres absolute). In the second series the VER (visual evoked response) was measured as well as the AER at 1 and 7 ATA, breathing the same two gas mixtures. The VER and AER were depressed at 7 ATA but there was no difference in the degree of this depression for either air or the oxygen-argon mixture. (Author)
