Effect of anesthetic doses of gamma-hydroxybutyrate on the acetylcholine content of rat brain. 1976

V H Sethy, and R H Roth, and J R Walters, and J Marini, and M H Van Woert

Gamma-hydroxybutyrate administered in anesthetic doses produces a time dependent increase in the levels of rat barin acetylcholine. A maximal increase in whole brain and subcortical levels of acetylcholine is observed about 15 min after administration of the lactone form of the drug. A similar GHB-induced increase in acetylcholine is observed in the striatum and a 75% increase in the hippocampus 15 min after administration of the drug. A good temporal correlation was not obtained between the increase in acetylcholine and the depth of anesthesia produced by the drug. Gamma-hydroxybutyrate did not cause a significant change in the striatal or hippocampal levels of choline. Possible mechanisms involved in the production of this increase in acetylcholine are discussed.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D003342 Corpus Striatum Striped GRAY MATTER and WHITE MATTER consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the THALAMUS in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The WHITE MATTER is the INTERNAL CAPSULE.

D000758 Anesthesia A state characterized by loss of feeling or sensation. This depression of nerve function is usually the result of pharmacologic action and is induced to allow performance of surgery or other painful procedures.
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
