Research published in *Fungal Biology* (2022) by Dr. Andrew Adamatzky from the University of the West of England revealed that fungi can communicate using electrical impulses, similar to how neurons in the brain transmit information. By analyzing the electrical activity across mycelial networks of four different fungal species, including *Pleurotus ostreatus* (oyster mushroom), the study identified patterns resembling a basic 'language' with a 'vocabulary' of up to 50 distinct impulses. This finding suggests a complex, previously unrecognized form of information processing within these organisms.

Why It’s Fascinating

We tend to think of communication in terms of sound, sight, or chemical signals. The discovery that fungi, ubiquitous yet often unseen organisms, employ electrical signaling akin to nervous systems is truly astounding. These electrical impulses, measured in microvolts, appear to be organized into 'words' and 'sentences,' suggesting a rudimentary form of information exchange within and between fungal colonies. The research analyzed patterns of electrical spikes, finding recurring sequences that could represent responses to environmental stimuli or signals to other parts of the network. This fundamentally challenges our perception of intelligence and communication in the natural world, pushing the boundaries of what we consider 'cognition.' If fungi can 'talk' using electrical patterns, what are they saying, and what does this imply about the consciousness of non-animal life? It invites a profound re-evaluation of the biological underpinnings of information transfer in life on Earth.
