The increase in SNA to BAT evoked by microinjection of bicuculline (Bic) into the RPa is attenuated by prior microinjection of methysergide into T2–T5 IML. Representative example (A) and group data (B) (means ± SE, n = 5) in which each point is the 30-s average of the variable values. ●, data before microinjection into the T2–T5 IML; ○, data following microinjection of methysergide into the T2–T5 IML. *P < 0.05, paired t-test between responses before and after microinjection of methysergide into T2–T5 IML.
