... drug intake are involved in mechanisms that facilitate relapse. It has been postulated that these neurotransmitter systems are related to changes in motivational and learning mechanisms, and engender a shift from goal-directed to habitual behavior in dependent patients that facilitates drug-seeking...

Extinction of learned behavior induces be- havioral ‘despair’, and is held to provide a conceptual and empirical model of human depression resulting from the withdrawal of reinforcement. We tested whether the neuroendocrinological and chemical concomitants...

The change in activation in the patient group correlated with a change in subjective sleepiness, while the increase in activation in the controls could be attributed to learning processes. Conclusion: We hypothesized...

To assess the alternative explanations of the performance decrements, rats received lesions in either CA1 or CA3 fields of dorsal and ventral hippocampus, respectively...
