It has been suggested that the cardiovascular responses to hypoxia are produced as integrated interactions between the effects of the autonomic nervous system and the direct effect of hypoxia on the central nervous system (CNS) and the cardiovascular system (Daly, 1986; Marshall, 1994). However, hypoxic exposure has been delivered for relatively short periods of time before attaining a steady state in many works. Therefore, such responses may have resulted before integrated interactions began operating. There is also no information on the behavior of the autonomic nervous activities during hypoxia in conscious animals, which may be relevant to the study of an integrated function. In this study, the autonomic nervous activities are examined during the cardiovascular responses of the chemoreceptor-intact and of denervated conscious rats to systemic hypoxia, in order to determine the contribution of the arterial chemoreceptors to these responses.
