[Progress in studies on the mechanism of substance addiction in central nervous system].

The mechanism of substance addiction in the central nervous system is the key point to solve the problem of drug addiction in clinical prophylaxis and treatment, but it has been obscure so far. Previous researches in this field suggested that the higher brain function of the learning and memory might be pivotal in understanding the mechanism of substance addiction.
