GABA is synthesized within GABA terminals through a highly compartmentalized process in which glial-derived glutamine is a major precursor and its release is modulated by GABA(B) autoreceptors. The aim of this work was to ascertain whether or not GABA synthesis and release are coupled in the rat brain through a GABA(B) autoreceptor-mediated modulation. It(More)
A method for the quantitation of L-glutamic acid in the picomole range was developed by finding conditions which allowed the production of NADH by the action of the L-glutamate dehydrogenase (EC 1.4.1.3) and its subsequent transformation to a highly fluorescent derivative. The method measures linearly glutamate from 250 pmol to 5 nmol. For its simplicity(More)
The glutamate decarboxylase activity in the rat cerebellum, frontal cerebral cortex, hypothalamus, substantia nigra and nucleus caudatus, was measured after either acute or chronic administration of (+)-amphetamine (1.35 and 5.4 mg/kg, i.p.). It was found that following 45 days of treatment the highest dose of the drug induced a selective increase of(More)
