  • The neuronal mechanisms of sneezing were examined in precollicular-postmammillary decerebrate cats. Mechanical stimulation (frequency 20 Hz, peak-to-peak displacement 0.5 mm) of the nasal membrane evoked a series of sneezes. In the same preparation, electrical stimulation (duration 0.2 ms, frequency 10 Hz, 5-50 microA) delivered to the lower brainstem also evoked sneezes. The changes in EMG activity and subglottic pressure during brainstem-induced sneeze were similar to those recorded nasal… CONTINUE READING
