This paper is the 28th consecutive installment of the annual review of research concerning
the endogenous opioid system, now spanning over a quarter-century of research. It …

Repeated treatment of psychotropic drugs produces changes in brain and behavior that far
outlast their initial neuropharmacological effects. The nature of persistent drug-induced …

Chronic exposure to opioids is the most common treatment plan to reduce the pain. In this
study, the stereotyped behaviors and cognitive functions related to different types of tactile …

Chronic exposure to morphine can impair performance in tasks which need sensory
processing. Using single unit recordings we investigate the effect of chronic morphine …

Morphine exposure may have a negative effect on the receptive field properties of neurons
in primary visual cortex of cats. The present experiment used morphological methods in …

Chronic exposure to opiates leads to maladaptive changes in various functions of the
mammalian brain, including properties of neuronal response in the visual pathway. In the …

Opiates disrupt neural functions in many brain areas, including visual cortex. Previous
studies have indicated substantial changes of many neuronal response properties induced …

药物成瘾所导致的行为和生理方面的长时程改变可能与相关脑区突触连接的重构有关.
安非他命, 可卡因, 吗啡和尼古丁滥用时, 精神依赖和奖赏效应相关脑区神经元的树突和树突棘的 …

Electrophysiological and biochemical studies have indicated that GABAergic modulation is
involved in the opioid-induced altering of response properties of visual cortical cells and …
