Microinjection of 5-HT1A or 5-HT7 receptor subtype-selective antagonists into the T2–T5 IML attenuates the SNA to BAT evoked by cold exposure. A: representative example. B and C: group data (means ± SE, n = 5) in which each point is the 30-s average of the variable values for WAY-100635 (B) and SB-269970 (C). Time zero represents the time at which the first microinjection of the antagonist was made into the IML. *P < 0.05, paired t-test of value at the maximal change compared with the initial value before microinjections into the IML.
