Effects of Exposure to Oxygen at High Barometric Pressure on Higher Functions of the C.N.S. ∗

Abstract

Conclusion

The data were interpreted to mean (1) that successive intermittent exposures to O₂ at high barometric pressure had no effect on the ability to learn a maze habit; (2) that the retention and memory of a maze previously mastered was adversely affected to a striking degree by intermittent exposures to increased O₂ pressure; (3) that certain mental processes may suffer deleterious effects as a result of exposure to increased O₂ pressure even when such exposure causes no evident motor dysfunction.
