the different responses of the vessels had some similar features in respect to threshold changes of the pco2 and po2 , to potentiation of effects of both parts of the brain vascular system on increased shifts of the blood gas tension , to greater sensitivity of both parts to pco2 changes , to effect of the blood gas tension on reactivity of both parts to noradrenaline .
