The MCPA-evoked sympathoexcitation and pressor response is not abolished by brain transection at the level of the CVLM. A, Glutamate (glu) microinjection into the MCPA evokes a large increase in ABP and sSNA before and after transection (transect) at the level of the CVLM. Transection causes a large decrease in ABP and sSNA. B, Site of glutamate microinjection into the MCPA described in A. Scale bar, 1 mm.
