pubmed:abstractText |
Antagonism of ethanol-induced depression of locomotion was observed after intracisternal injection of thyrotropin releasing hormone (TRH) and bicuculline methiodide (BICM), as well as after microinjection of these drugs into the medial septum. The present investigation compared the behavioral and physiological consequence of administering TRH and BICM into the medial septum, inferior colliculus and substantia nigra to quantitate the similarities between these compounds. BICM produced a major increase in locomotor activity when injected into the medial septum and stereotypies when injected into the substantia nigra, suggesting that GABA-containing neurons have widespread influences on motor function. The wild running and seizure activity observed after BICM injection into the inferior colliculus was also consistent with this latter view. The marked increase in rectal temperature observed when BICM was injected into the medial septum may also implicate GABAergic mechanisms in temperature control at this brain site. TRH produced no such behavioral or physiological changes when administered into these three sites. Thus, this work strongly suggests that TRH does not exert a widespread action as a GABA antagonist because TRH did not produce the same changes induced by BICM. The actions of BICM and TRH to antagonize ethanol-induced depression when microinjected into the medial septum suggests that this brain area may be a critical site for the depressant action of ethanol.
