Sensitization refers to augmented behavioral responses produced by repeated, intermittent
injections of dopaminergic psychostimulants. The locomotor manifestations observed after a …

Repeated exposure to drugs classed as psychostimulants can produce behavioral
sensitization, defined as augmented motor responses to fixed doses of such compounds …

The present study examined post mortem changes in central dopaminergic terminal regions
following acute or chronic treatment regimens with the dopamine D2/D3 receptor agonist …

Sensitization of dopaminergic neural reward circuits has been hypothesized to be involved
in the development of drug addiction. Highly palatable foods activate these same brain …

To assess whether locomotor sensitization induced by repeated injections of the dopamine
agonist quinpirole reflects tolerance of the drug's presynaptic depressive effects on …

The study tested whether differences in locomotor activation during chronic treatment result
in differential behavioral sensitization induced by the D2/D3 dopamine agonist quinpirole …

Chlorisondamine blocks central nicotinic receptors for many weeks via an unknown
mechanism. Intracerebroventricular administration of [3H]‐chlorisondamine in rats results in …

To assess whether the interval between injections affects the course of locomotor
sensitization to quinpirole, groups of rats were injected every 2, 4, or 8 days with quinpirole …
