Sympathetically-mediated cardiovascular responses induced by neurochemical microinjection in the brainstem lateral tegmental field of cat.
This study examines sympathetically-mediated cardiovascular responses arising from microinjections of AMPA and kynurenic acid in the medullary lateral tegmental field (LTF). The resulting behavior, which is predominantly inhibitory, is nearly identical to that reported for the para-ambiguual area lying just lateral to the LTF, and suggests that the two regions may share other cardiovascular control functions.
