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。
