Actual measurement of carbon dioxide perception was accomplished through use of electrophysiological techniques. The effects of species, sex, age, humidity, temperature and ambient C02 concentration on carbon dioxide perception were determined and statistically analyzed.application/pdfCopyright is held by the author who has granted the Oklahoma State University Library the non-exclusive right to share this material in its institutional repository.
