315. 哺乳动物耳蜗离体存活与听觉力学发现

from 知为谁 · host 知为谁

这篇文章详细介绍了洛克菲勒大学科学家的一项重大突破,该团队首次成功地将哺乳动物的耳蜗组织在体外维持活性并记录了其听觉机制。这项工作由已故的A. James Hudspeth及其团队完成,实现了对耳蜗功能的实时直接研究,这在以前由于该器官的脆弱性和不可接近性是无法做到的。通过使用一个特殊的定制装置,研究人员证实了霍普夫分岔(一种机械不稳定性)是哺乳动物听觉放大过程中的关键生物物理原理,这与其他物种的听觉机制相似。这项突破被认为是生物物理学领域的一项杰作,为研究听力损失的治疗方法提供了一个前所未有的工具。内容来源:https://scitechdaily.com/a-masterpiece-for-the-first-time-scientists-keep-a-mammalian-cochlea-alive-outside-the-body/
