The method of inhalation has also been reported to affect the pattern of the EEG. Nasal inhalation produces greater anterior/posterior diversity in beta than does mouth inhalation and appears to reduce left-hemisphere alpha (Lorig et al., 1988). Lehmann and Knauss (1976) reported increased desynchrony as a result of inhalation of room-air while others have demonstrated a correlation between increased EEG amplitude in one hemisphere to the contralateral nostril stimulated during inhalation of room-air (Werntz et al., 1983), as noted in Chapter 3. The respiratory mode of the subjects in EEG experiments is, therefore, important.
