Feeding behavior is known to have potential to alleviate pain. We recently demonstrated that both 24 h fasting and 2 h refeeding (food intake after 24 h fasting) induce analgesia in inflammatory pain conditions via different brain mechanisms. However, brain structures that distinctly involved fasting- and refeeding-induced analgesia is still unknown. Hence, this study is aimed to reveal brain structures mediating fasting- and refeeding-induced analgesia.

急性和慢性炎症性疼痛状况下对进食行为的脑 c-Fos 表达模式。

众所周知，进食行为具有减轻疼痛的潜力。我们最近证明，24 小时禁食和 2 小时再喂食（24 小时禁食后的食物摄入）通过不同的脑机制在炎症性疼痛条件下诱导镇痛。然而，明显涉及禁食和再进食诱导的镇痛的大脑结构仍然未知。因此，本研究旨在揭示介导禁食和再进食诱导的镇痛作用的大脑结构。
