while nerve activity and epinephrine and norepinephrine secretion were not significantly altered by the change in blood pressure in baroreceptor denervated animals , there were increases in these variables ( 131.1 % of control levels for epinephrine , 117.5 % for norepinephrine , and 127.1 % for nerve activity ) in response to bleeding and a marked decrease ( to 63.0 % of control levels for epinephrine , 53.9 % for norepinephrine , and 54.0 % for nerve activity ) in response to phenylephrine administration with baroreceptors intact .
