Stimulation with bipolar electrodes of specific loci in stellate ganglia elicited in anesthetized piglets, 1-4 weeks of age, alterations in cardiac function and aortic pressure. Responses were also elicited by chemical stimulation in specific loci of these ganglia. The probability of eliciting a cardiovascular response by stimulating loci in a stellate(More)
In developing kittens, antagonism of N-methyl-D-aspartate receptors by systemic injections of MK-801 produced: (a) blockage of the inspiratory off-switch, prolonging phrenic and hypoglossal discharges; (b) age-dependent changes of sympathetic inspiratory discharges, elimination of inspiratory-related discharges in animals less than or equal to 36 days old(More)
