Amphetamines are psychostimulant drugs with high abuse potential. Acute and chronic doses of amphetamines affect dopamine (DA) neurotransmission in the basal ganglia. The basal ganglia are a group of subcortical nuclei that are anatomically positioned to integrate cognitive, motor and sensorimotor inputs from the cortex. Amphetamines can differentially alter the functioning of specific BG circuits to produce neurochemical changes that affect cognition, movement, and drug seeking behavior through their effects on DA neurotransmission. This review focuses on how alterations in dopaminergic neurotransmission within distinct basal ganglia pathways can modify their functional output to predict and explain the acute and long term behavioral consequences of amphetamine exposure.
安非他命是具有高度滥用潜力的精神刺激药物。急性和慢性剂量的安非他命会影响基底神经节中的多巴胺(DA)神经传递。基底神经节是一组皮质下核团,其解剖位置能够整合来自皮质的认知、运动和感觉运动输入。安非他命可以差异性地改变特定基底神经节回路的功能,通过其对DA神经传递的影响产生影响认知、运动和觅药行为的神经化学变化。本综述重点关注不同基底神经节通路中多巴胺能神经传递的改变如何改变其功能输出,以预测和解释安非他命暴露的急性和长期行为后果。
