1·Conclusi on: the firing of ventral pallidal neurons is excited prominently from morphine in the morphine dependent rats. Ventral pallidum has an important role in drug reward.
结论：吗啡显著兴奋吗啡依赖大鼠腹侧苍白球神经元，腹侧苍白球在药物强化过程中起着重要作用。
2·Methods:The firing of ventral pallidal neurons in the action of morphine and naloxone was recorded and analyzed in the morphine dependent rats with extracellular single-unit recording.
方法：通过单细胞细胞外记录吗啡依赖大鼠腹侧苍白球的电信号，观察吗啡对放电的影响。
