Abstract
Repeated administration of cocaine lowers the basal extracellular levels of glutamate in the nucleus accumbens as measured by microdialysis. The studies presented reveal that this long-term neuroadaptation elicited by repeated cocaine results from a decrease in the activity of cystine/glutamate exchange.
摘要
通过微透析测量发现，反复给予可卡因会降低伏隔核中谷氨酸的基础细胞外水平。所呈现的研究表明，反复使用可卡因引发的这种长期神经适应性变化是由于胱氨酸/谷氨酸交换活性降低所致。
