Glutamate and aspartate are the primary neurotransmitters of projections from motor and premotor cortices to the striatum. Release of glutamate may be modulated by dopamine receptors located on corticostriatal terminals. The present study used…

Previous work has demonstrated a complex neurochemical and neuroanatomical heterogeneity of the striatum in normal brains. The present research investigated whether the heterogeneous distribution of dopamine would be altered following unilateral…

The neurochemical heterogeneity of the rat striatum was assessed in vivo by measuring subregional changes in extracellular dopamine and DOPAC by in vivo electrochemistry and microdialysis in response to amphetamine and the D2 antagonist,…

The effects of the recently classified Schedule I amphetamine analog, 3,4-methylenedioxymethamphetamine [+/-)-MDMA) on caudate and nucleus accumbens dopamine release and metabolism were studied by in vivo voltammetry and HPLC with electrochemical…

Specific behaviors comprising the serotonin syndrome (low body posture, forepaw treading, headweaving) and the autonomic signs of piloerection and salivation were determined and analyzed with locomotor activity in response to MDMA at three doses…

The effects of (-)cathinone, the primary psychoactive alkaloid of the Khat plant, were compared to those of (+)amphetamine in the anterior caudate-putamen and the nucleus accumbens. In vivo microdialysis was used to measure extracellular levels of…

The effects of thiamine thiazolone (TT) and thiamine thiazolone pyrophosphate (TTPP) on the in vitro and in vivo inhibition of pyruvate dehydrogenase complex (PDHC) from rat cortex and hippocampus were characterized. TTPP decreased PDHC activity in…

The neurochemical and anatomical heterogeneity of dopamine uptake blockade was studied at a medial and lateral position in each of 3 rostrocaudal areas of the rat caudate-putamen. In vivo voltammetric measures of extracellular dopamine indicated a…

A rapid microassay is described for the measurement of biogenic amines using an isocratic HPLC system with electrochemical detection. Catecholamines, indoleamines and their major metabolites were extracted with 150 microliters of perchloric acid from…

An improved, HPLC with electrochemical detection method for the isocratic separation and determination of amino acids from post-mortem brain tissue and from microdialysates of awake-behaving animals is described. Optimal conditions that maximize…
