Now, the first night of less sleep may actually trigger the mesolimbic system, releasing dopamine and giving you a sense of adrenaline.

现在，第一个睡眠不足的晚上可能会触发中脑边缘系统，释放多巴胺，让你感觉肾上腺素上升。

For example, increased dopamine in the mesolimbic system, a reward pathway composed of the ventral tegmentum and the nucleus accumbens causes pleasure, improved attention and mental processing, and working memory.

例如，人体的一个由腹侧被盖区和伏隔核组成的奖赏通路中脑边缘系统里多巴胺的增多，可以引起欣快感、注意力提高、思维变敏捷、记忆力增强等效应。

Greater curiosity led to better retention on both tests; brain scans showed increased activity in the mesolimbic dopamine system, a reward pathway, and in the hippocampus, a region that matters for forming new memories.

更强的好奇心会让他们在这两个测试中表现出更好的记忆力，而脑扫描则显示中脑缘的多巴胺系统（奖励通路）以及海马区（与形成新记忆有关的区域）的活动增加了。
