The contribution made by specific dopamine receptor subtypes to the induction of motor
behaviors has not been firmly established. Here, we first characterized the behavioral effects …

The noncompetitive NMDA receptor antagonist MK801 (dizocilpine) produces behavioral
stimulation mediated, in part, through indirect activation of the dopamine (DA) system …

In the present study, we investigated the effect of adrenocorticotropic hormone (ACTH) on
the immobilization of rats in the forced swim test after the administration of selegiline, a …

It is established that dopamine (DA) is an important brain mediator of the behavioral (ie
sensitizing) effects of cocaine in rodents. Among DA receptors, recent findings point to …

Rationale Operant timing behaviour is sensitive to dopaminergic manipulations. It has been
proposed that this effect is mediated principally by D 2-like dopamine receptors. However …

The paper examined the effect of 7-OH-DPAT (7-hydroxy-N, N-di-n-propyl-2-aminotetralin),
a dopamine D 3 receptors-prefering agonist, on the catalepsy evoked by reserpine …

Previous studies have shown that antidepressant drugs with different pharmacological
profiles, administered repeatedly, increase the locomotor hyperactivity induced by various …

The aim of this study was to examine behavioral and biochemical effects of nafadotride, the
new dopamine D! receptor antagonist, and to compare it with haloperidol (dopamine D …

The administration of nafadotride, given at doses known to block the D 3 dopamine
receptors (0.75, 1.5, 3 mg/kg ip) increased locomotor activity both in naive and habituated …

Mu opioid receptor agonists such as morphine stimulate the release of dopamine (DA) in
various brain regions. These increases in DA are thought to be involved in some of the …
