Martin Picard: 我主要研究线粒体与心理之间的联系,以及线粒体如何影响我们的生活和体验。线粒体不仅仅是细胞的能量工厂,它们还具有多种功能,包括产生信号、调节基因表达和决定细胞命运。基因模型在生物学和健康科学领域具有误导性,它高估了基因对健康的影响,而忽视了我们与世界的互动。我认为,我们应该将身体视为一个社会集体,细胞之间的连贯性是健康的关键。癌细胞打破了社会契约,不再接收身体其他部分的信息,它们的目标是分裂和繁殖,而不是维持有机体。线粒体驱动细胞的能量流动,并对细胞的命运有否决权,它们就像细胞内的迷你大脑,决定细胞的命运。促进身体不同部位的社交性可能对健康有益,锻炼就是一种方式。锻炼对身体是一个挑战,需要身体各部分协同工作。生物学朝着更高的效率进化,细胞和器官之间的社交性是关键。线粒体为大脑和思维提供能量,思维是一种能量模式,精神健康障碍是大脑的代谢紊乱。生酮饮食可以通过改善能量流动来改善精神疾病症状。线粒体曾经是一种细菌,后来与更大的细胞合并,成为细胞的一部分,线粒体的获得使得细胞间的通讯成为可能,并触发了多细胞生命的出现。线粒体来自母亲,母性能量通过线粒体传递。

Mitochondria are known as the powerhouse of the cell—but new research suggests they might be far more complex. Columbia University’s Martin Picard joins Scientific American’s Rachel Feltman to explore how these tiny organelles could be communicating and what that might mean for everything from metabolism to mental health.
