914. 记忆可以传递——或者被吃掉吗?

from 知为谁 · host 知为谁

这篇文章探讨了记忆是否可以通过生物化学方式转移的历史谜团,重点关注了20世纪60年代詹姆斯·麦康奈尔极具争议的平涡虫实验。麦康奈尔当时声称,通过让未经训练的蠕虫吞食已受训蠕虫的组织,可以实现记忆的“同类相食”转移。然而,现代神经科学家在试图复制这些实验时遭遇了失败,因为如今的平涡虫似乎表现出无法被制约学习的特征。尽管如此,当代对海兔和圆虫的研究发现,RNA和遗传物质确实可以在个体间传递特定行为,这为麦康奈尔早期的直觉提供了部分现代科学支撑。这一科学史的回顾不仅审视了记忆的物理载体,也揭示了科学实验在可重复性方面面临的复杂挑战。内容来源:https://www.quantamagazine.org/are-memories-transferable-or-edible-20260605/
