Role of carotid chemoreceptors in responses induced by obstructive apnea.

<p>A. Apnea-induced responses in WKY (n = 13) and SHR (n = 14) rats, before and two days after section of the carotid body arteries. Error bars indicate SEM. MAP = mean arterial pressure, HR = heart rate, TP = thoracic pressure. B. Average responses to apnea. * indicates difference from before inactivation; † indicates difference between strains (Bonferroni, p<0.05).
