title: Effects of hypoxic blood on baroreceptor activity in the dog.
abstract: The effects of perfusing arterial baroreceptors with venous blood have been tested on eleven single fibres in nine dogs using a discrete pouch preparation. The frequency of discharge on the afferent baroreceptor fibres was not altered by the composition of blood perfusing them. It is concluded that the reduction in impulse discharge from these baroreceptors during sympathetic nerve stimulation is probably not due to anoxia (or reduced blood flow) at the nerve terminals.
