整合了人类脑细胞的小鼠皮层显示出认知能力的提高

斯坦福大学的研究人员通过用人类细胞替换其大部分大脑皮层,开发出了“异种皮层小鼠”。这些经过改造的小鼠,缺乏大部分自然皮层和海马体,在记忆测试中的表现优于对照组小鼠。这项发表在《自然》杂志上的研究,突显了类器官技术的进步,并引发了关于此类动物模型潜在人类意识的伦理考量,科学家们警告不要在灵长类动物身上进行类似实验。 AI

影响 展示了先进的类器官技术,在研究脑损伤方面具有潜在应用,并引发了关于人类与动物认知界限的伦理问题。

    认识一种大脑皮层由人类细胞组成的小鼠

    Multiple cameras tracked a mouse as it wandered around a small arena. A computer charted its position and speed, leaving Pong-like traces on a monitor.&#160; The reason to watch this rodent so carefully? Nearly half its brain volume had been replaced with human cells. The effort …
