Behavioral sensitization is a progressive, enduring enhancement of behaviors that develops
following repeated stimulant administration. It is mediated in part by dopaminergic pathways …

Behavioral sensitization to psychostimulants manifests as an increased locomotor response
with repeated administration. Dopamine systems are accepted to play a fundamental role in …

Behavioral sensitization is a well-studied model of behavioral plasticity mediated at least in
part by dopaminergic systems believed to play an important role in several psychiatric …

While a range of dopamine D2‐related behaviors are exaggerated in amphetamine‐
sensitized animals, studies of the dopamine D2 receptor have reported either no change or …

Behavioral sensitization, the progressive and enduring augmentation of certain behaviors
following repetitive drug use, alters rodent locomotion in a long-standing manner. The same …

Hedonic and reinforcing properties of drugs of abuse are closely related to brain dopamine
neuron activity. All these drugs increase dopamine release in the shell of nucleus …

Mice lacking the dopamine D4 receptor subtype (D4R−/−) are supersensitive to
methamphetamine and cocaine. We sought to expand and refine earlier experiments …

The sensitizing properties of drugs of abuse have been proposed to play an important role in
the persistence of drug seeking behavior. We decided to evaluate the temporal relationship …

A study was performed to examine behavioral response to a challenge of selective
dopamine D-1 and D-2 agonists in rats previously sensitized by subchronic administration of …

The central dopamine system plays significant roles in motor activity and drug‐induced
behavioural sensitization. Our goal was to determine the significance of dopamine D3 …
