Introduction: The hippocampus (HIP), the primary brain structure related to learning and memory, receives sparse but comprehensive dopamine innervations and contains dopamine D1/D2-like receptors. It is demonstrated that dopamine receptors in dentate gyrus (DG) region of HIP have a remarkable function in spatial reward processing. Much less is known about the involvement of HIP and its D1...

Introduction: Herein, we evaluated linkages between EFs performances and dopamine receptor (DR)  mRNA and testosterone level in the young Iranian male people. Methods: All 140 participants were normalized using depression, anxiety and stress scale questionnaire. Remained 108 volunteers were tested against drug abuse and then volunteers were distinguished by Wisconsin Card Sorting Test (WSC...

Dopamine receptor D2, also known asD2R, is a protein that, in humans, is encoded by the DRD2 gene.The dopamine D2 receptor was discovered in 1975 by Philip Seeman who had named it as the antipsychotic/dopamine receptor [1] The dopamine D2 receptor is the main receptor for all antipsychotic drugs. Any drug that does not interfere with dopamine action at the D2 receptor does not have an antipsych...

In the present study, interactive effects of D1 and D2 dopamine receptors antagonists and different periods of lithium pretreatment on morphine dependence in mice have been investigated. This study was designed to investigate whether the hypothesis that lithium and dopaminergic mechanisms via their effects on phosphoinositide pathways and calcium flux could influence morphine withdrawal respons...

background: non motor symptoms (nms) of idiopathic parkinson’s disease (pd) are a major cause of disability and recognition of these symptoms and treatment is important for comprehensive health care. deep   brain   stimulation   of   bilateral   subthalamic nucleus deep brain stimulation (stn dbs) has been shown to improve motor symptoms in pd and effects on nms are unknown. to investigate the ...

ntipsychotics have long been linked with hyperprolactinemia. This phenomenon was first considered a drug class effect, but the arrival of clozapine, better deliniation of dopamine receptor subtypes, and identification of the four principal CNS dopamine pathways revealed that hyperprolactinemia was not a universal consequence of antipsychotic use. We now know that most atypical antipsychotics ar...

The non-catechol, selective dopamine D2-agonist compound 3H-205-502 was used to localize dopamine D2 receptors by autoradiography after in vitro labeling of brain sections. The characteristics of the binding of this ligand to tissue sections were those expected from the labeling of dopamine D2 receptors. The binding of 3H-205-502 was inhibited selectively and stereospecifically by dopamine D2 a...

The mesolimbic system is known to play a role in self-administration of opioids and psychostimulants. Although morphine and cocaine act by separate cellular mechanisms initially, the present study describes a common change in synaptic regulation of dopamine cells in the ventral tegmental area 1 week after termination of chronic treatment with either drug. Normally, D1 receptor activation augmen...
