The release of endogenous glutamate and aspartate from corticostriate neurons in the anaesthetized rat was investigated. Efflux of glutamate, aspartate and leucine in push-pull cannula perfusates of the striatum was measured in 1 min fractions collected before, during and after a 4 min stimulation period of ipsilateral frontal cortex. Efflux of the putative(More)
Concentrations of putative neuroactive substances glutamate, aspartate, gamma-aminobutyric acid, glycine, proline and ethanolamine were determined in ventricular cerebrospinal fluid collected in patients suffering from Parkinson's disease, pain syndromes or cerebellar tremor. Values are similar to those given in the literature for lumbar cerebrospinal(More)
Release of ethanolamine, serine, and choline in rat pontine nuclei on electrical stimulation of afferents from the cortex was investigated using in vivo push-pull cannula techniques. Ethanolamine was determined by using gas chromatographic techniques; serine was measured with a HPLC system; and choline was assayed with a luminescence method. Resting elution(More)
