从真菌电脉冲活动中推导出的真菌语言
Language of fungi derived from their electrical spiking activity

导读
这篇论文分析真菌菌丝中记录到的电脉冲信号,尝试将其类比为语言,用信息论方法提取词汇、句长等语言学统计特征,发现不同真菌物种的信号具有类似人类语言词频分布的规律。作者提出真菌电信号可能构成一种交流'语言'的假说。
HN 关注点:真菌电信号是否构成'语言'触及意识、生物通信等迷人话题,HN 读者既好奇其科学性,也在讨论解读边界——是发现还是类比。

支持专业解读:真菌具备动作电位样信号是趋同演化,暗示其信号机制可能与神经系统有深层相似性
神经科学博士在此。论文引用中提到真菌会表现出可被胞内和胞外记录检测到的动作电位样脉冲串,这点很突出。动作电位是神经元的基本信号机制——细胞主动消耗能量快速传递信息的电信号。许多细胞都用电位传递信号,但大多是被动、渐进式的扩散。看到这种(我猜的)趋同演化真的很酷,可以想象未来几十年我们会从真菌和菌丝网络中学到多少新东西。认真说,蘑菇有可能是 conscious 的。

Neuro PhD here. I haven't read the entire paper but this citations stands out: > Fungi also exhibit trains of action-potential-like spikes, detectable by intracellular and extracellular recordings Action potentials are the fundamental signaling mechanism used by neurons [1]. Think of them as an electrical signal that a cell actively propagates. Lots of cells use electrical potentials for signaling; however, most of them spread gradually or passively. Action potentials on the other hand the cell actively expends energy to send information quickly. Really cool to see convergent biology (my personal guess) here. I can only imagine what new things we're going to learn about fungi and mycelium in the next few decades. In all seriousness mushrooms COULD be conscious. 1 - https://en.wikipedia.org/wiki/Action_potential
补充补充资料:推荐《Entangled Life》,书中探讨了菌丝网络作为类神经系统的假说
推荐一本书:Merlin Sheldrake 的《Entangled Life》。作者讨论了地下相互连接的菌丝网络通过电信号彼此通信、充当一个巨大神经系统的可能性。他克制地没有称之为'巨型大脑',但承认鉴于我们对真菌已有的了解,这种可能性并不牵强。这本书非常棒,强烈推荐。

Book recommendation: "Entangled Life" by Merlin Sheldrake [0]. The author discusses the possibility of intricately connected subterranean mycelium networks electrically signaling each other acting as a giant nervous system. He stops himself from calling it a giant brain, but admits that the possibility isn't really far fetched given everything else that we know about fungi. It's a fantastic book. Strong recommend.

质疑质疑澄清:论文并未证明电信号是语言,只是假设其为语言后计算统计特征
这确实是一篇有趣的论文,但要指出:他们的发现并不是'脉冲活动是一种语言'。他们只是提出它可能是语言,然后为了论证的缘故,把它当作语言来处理并推导出一系列统计量。至少我从摘要和引言中是这么理解的。

It's absolutely an interesting paper, but just to note: Their finding is not that the spike activity is a language. They just propose it might be a language and then derive a number of statistics by treating it like a language for the sake of the argument. ... at least that was my understanding from the abstract and introduction.
补充背景科普:真菌的分解能力对地球生态演化至关重要
人们没有意识到真菌有多重要。曾有一段时期树木是新事物而真菌尚未演化——史前树木基本占领了整个星球,地面上没有任何东西能分解堆积如山的枯木,到处是一层层的死树。后来真菌演化出来开始分解这一切,很久之后才有了动物。

People do not realize just how important Fungi are - there was a point at which Trees were the new hotness and Fungi had not evolved yet - prehistoric trees basically took over the entire planet and there was nothing to break down all of the leftover dead wood on the ground. We are talking layers and layers of dead trees everywhere. Then Fungi evolved and started breaking all that down and eventually a long time later we get animals.
