The central dopamine system plays a prominent role in the effect of psychostimulants such as methamphetamine, cocaine and nicotine. l-3,4-Dihydroxyphenylalanine (DOPA), a precursor of dopamine, has been proposed as a neurotransmitter in the central nervous system. We have studied the effects of these psychostimulants on the release of DOPA and dopamine from(More)
We have proposed the hypothesis that L-3,4-dihydroxyphenylalanine (DOPA) plays a role of neurotransmitter of the primary baroreceptor afferents terminating in the nucleus tractus solitarii (NTS). In the present study, we tried to clarify whether glutamate receptors and/or nitric oxide (NO), important modulators for central cardiovascular regulation, are(More)
We investigated whether stress induces the release of L-3,4-dihydroxyphenylalanine (DOPA) and dopamine from the nucleus accumbens in conscious rats and characterized the stress-induced response. Electrical foot-shock stress induced both DOPA and dopamine release, measured by microdialysis, from the nucleus accumbens in freely moving rats. Pretreatment of(More)
