S 14506 (1-[-(4-fluorobenzoylamino)ethyl]-4-(7-methoxynaphthyl)piper azine hydrochloride), 8-OH-DPAT ((+/-)-8-hydroxydipropylaminotetralin hydrobromide), clozapine and raclopride were compared in some behavioural models able to characterize dopamine antagonist properties. In mice treated with apomorphine (0.75 mg/kg, s.c.), stereotyped climbing and sniffing were dose dependently antagonized by
Improving exercise capacity during adolescence impacts positively on cognitive and motor functions. However, the neural mechanisms contributing to enhance physical performance during this sensitive period remain poorly understood. Such knowledge could help to optimize exercise programs and promote a healthy
The effects of chronic treatment with dopamine (DA) D1 and D2 receptor antagonists were evaluated in eight cebus apella monkeys with mild oral dyskinesia after previous haloperidol treatment. SCH 23390 (D1 antagonist) was given daily to investigate the direct behavioural
Prolonged treatment with dopamine D2 receptor antagonists is known to elevate the density of dopamine D2 receptor binding sites in caudate-putamen and nucleus accumbens in rat and human brain. In this study we used the dopamine D2 receptor antagonist raclopride
Phasic dopamine activity is evoked by reliable predictors of food reward and plays a role in cue-triggered, goal-directed behavior. While this important signal is modulated by physiological state (e.g. hunger, satiety), the mechanisms by which physiological state is integrated by
