Fungi Use Electrical Signals to Communicate Like Words

Next time you walk through a forest, consider what is happening beneath the soil. Scientists have discovered that fungal networks send electrical impulses to one another. Even more surprising, these signals group together in patterns that closely resemble human language structures. Mushrooms might actually be talking.

The Science Behind Mushroom Chatter

In April 2022, a study published in the journal Royal Society Open Science caught the attention of biologists worldwide. Professor Andrew Adamatzky, a researcher at the Unconventional Computing Laboratory at the University of the West of England in Bristol, led the research. He wanted to see if the electrical activity found in fungi shared any mathematical similarities with human speech.

Adamatzky inserted tiny microelectrodes into the substrate colonized by four specific species of fungi. These included the enoki, the split gill, the ghost fungus, and the caterpillar fungus. By recording the electrical output over several days, he noticed distinct spikes in the data. These were not random bursts of static energy. The spikes clustered together in highly specific sequences, much like how letters form words and words form sentences.

How Fungi Send Messages

To understand how this works, you have to look at the physical structure of fungi. The mushrooms we see above ground are just the fruiting bodies. The main organism lives underground as a massive network of root-like threads called mycelium.

These mycelial networks can stretch for miles. They connect different fungal colonies and even link up with the roots of nearby trees. When Adamatzky monitored these threads, he found that electrical impulses travel along them constantly. This mechanism is incredibly similar to how the human nervous system transmits messages.

When a human brain sends a signal to move a finger, it sends electrical impulses traveling through neurons. Fungi seem to be doing the exact same thing across their mycelial threads. They use channels that allow charged particles like calcium to flow in and out of their cells, generating small electrical currents that move rapidly down the network.

A Vocabulary of 50 Words

The most shocking part of the Bristol study is the math behind the electrical spikes. Adamatzky analyzed the duration and grouping of the impulses. He found that the patterns matched the structural rules of human vocabularies, particularly concerning word length and frequency.

Based on the recorded data, the fungi appeared to use a vocabulary of up to 50 distinct “words.” However, they do not use all 50 words equally. A core vocabulary of about 15 to 20 words makes up the bulk of their daily communication.

Different species showed drastically different levels of complexity.

• Split Gill Fungus: This species (Schizophyllum commune) produced the most complex and varied electrical patterns. It naturally grows on decaying wood and seems to have a highly active communication style.
• Ghost Fungus: Known for its striking bioluminescence, this fungus (Omphalotus nidiformis) also showed strong, consistent electrical spikes.
• Enoki and Caterpillar Fungi: These species showed much simpler, less frequent signaling patterns during the observation period.

What Are They Talking About?

If fungi are sending messages, what exactly are they discussing? Researchers have a few strong theories based on fungal ecology.

First, these signals likely involve food discovery. When one part of a mycelial network encounters a rich food source like a decaying log, it might send a signal to the rest of the network. This tells the organism to direct growth and energy toward that specific, nutrient-dense area.

Second, the spikes might act as warning signals. If a section of the network is damaged by insects or environmental stress, it can fire off rapid electrical pulses. This serves as an alert to the rest of the fungus to prepare for defense or repair mechanisms.

Finally, Adamatzky suggests these signals might just be a way for the fungus to maintain its identity. He compares it to wolves howling at night. The fungi might simply be checking in to ensure all parts of the massive underground network are still connected and functioning properly.

Is It Really a Language?

While the idea of talking mushrooms is exciting, many biologists urge caution. Equating electrical spikes to human words is a massive leap, and the scientific community requires more proof before rewriting biology textbooks.

Dan Bebber, a mycologist at the University of Exeter, notes that while the electrical pulses are entirely real, their true purpose is not fully proven. Bebber points out that these rhythmic pulses could simply be a side effect of nutrient transport. Fungi move water and nutrients across their networks in pulsing waves. The electrical spikes recorded in the Bristol lab might just be the physical mechanics of the fungus pushing food from one end to the other.

Before scientists can officially declare that fungi possess a language, they need to decode what specific spikes mean. Until a researcher can prove that a specific spike pattern always results in a specific biological action, the translation remains theoretical. Still, the existence of highly organized electrical activity proves that fungi are far more complex and interactive than we previously thought.

Frequently Asked Questions

Do all mushrooms communicate with electrical signals? Current research indicates that many fungi generate electrical impulses, but scientists have only tested a small fraction of species. The complexity of these signals varies wildly from one species to another.

Can humans understand fungal language? Not currently. Scientists can measure the electrical spikes and map their patterns, but we do not know what the signals mean. Translating these patterns into actionable data is the next major hurdle in mycological research.

What is mycelium? Mycelium is the vegetative part of a fungus. It consists of a branching, web-like network of fine white filaments called hyphae. It lives mostly underground or inside decaying material, acting as the digestive and communication system for the fungus.
