这项研究强调了嗅觉在食欲调节和肥胖发展中的重要作用。新发现表明，食物的气味在日常饮食习惯中 扮演了关键角色。更重要的是，这条神经通路只在体重正常的小鼠中能降低食欲，而在肥胖小鼠中失 效，这为预防肥胖小鼠暴饮暴食开辟了一条新途径。 美食当前，有人却说"闻着都感觉饱了"？据《自然·代谢》杂志11日报道，德国马克斯·普朗克代谢研究 所团队通过动物实验发现，一种新的神经细胞网络是造成这一现象的原因。这也揭示了嗅觉是如何影响 进食行为的，为肥胖症的预防和治疗提供了全新思路。 团队通过脑部扫描技术，在小鼠大脑的内侧隔膜中发现了一组新的神经细胞。当小鼠闻到食物气味时， 这些神经细胞会被激活，并产生饱腹感。由于这些神经细胞与负责嗅觉的嗅球直接相连，因此这个过程 会在几秒钟内完成。这些神经细胞很"馋"，对多种食物气味敏感，却不会对其他无关气味作出反应。 有趣的是，当小鼠开始进食后，这些神经细胞的活性会被抑制，这保证了正常的饮食过程。这些神经细 胞如果活跃，则会有效缩短进食时间，有助于野外小鼠减少被捕食的风险。 然而，在肥胖小鼠身上，这种神经细胞对食物气味的反应明显减弱甚至缺失，导致它们闻到食物香味时 并不会感到饱，进食量也没有 ...
