Mushrooms are a fungus, and a recent topic of interest in mycology (the study of fungi) is whether mushrooms have a nervous system. While mushrooms do not have a central nervous system, new research has found that they may communicate with each other using electrical impulses transmitted through thread-like filaments called hyphae. These filaments form a thin web called a mycelium that links fungal colonies within the soil. This network is similar to an animal nervous system and may allow mushrooms to communicate with each other using a type of language.

What You'll Learn
Mushrooms lack a nervous system
Mushrooms are part of the Fungi kingdom, which is separate from the Animalia kingdom. Unlike animals, mushrooms do not have a central nervous system. In fact, they are about as conscious as plants. Mushrooms do not show any signs of distress when they are plucked, chopped up, or eaten. This is because, unlike animals, they cannot feel pain.
The mushroom that we see is not an entire organism. It is the fruiting portion of a network of mycelium that lives underground. This network is formed by thread-like filaments called hyphae. The hyphae react to their environment, pursuing food and recognizing threats. They are able to do this without a nervous system.
Despite lacking a nervous system, mushrooms seem to transmit information using electrical impulses. These impulses travel across the hyphae, which form a thin web called a mycelium that links fungal colonies within the soil. These networks are remarkably similar to animal nervous systems.
Recent research by computer scientist Andrew Adamatzky at the University of the West of England suggests that mushrooms have an electrical "language" of their own. According to the study, fungi might use human-like "words" to form human-like "sentences" to communicate with each other. The complexity of the languages used by different species of fungi appears to differ, with the split gill fungus (Schizophyllum commune) using the most complicated lexicon of those tested.

Fungi communicate using electrical impulses
Mushrooms are the above-ground, sporing fruit of a fungus, connected to the large organism by a root network called mycelium. Fungi do not have a nervous system, but they do transmit information using electrical impulses across thread-like filaments called hyphae. These filaments form a thin web called a mycelium that links fungal colonies within the soil. These networks are similar to animal nervous systems.
Computer scientist Andrew Adamatzky from the University of the West of England's unconventional computing laboratory in Bristol conducted research on this topic. He inserted tiny microelectrodes into substrates colonised by their patchwork of hyphae threads, their mycelia. He found that the electrical spikes generated by the fungi often clustered into trains of activity, resembling vocabularies of up to 50 words. The distribution of these "fungal word lengths" closely matched those of human languages.
Adamatzky's research also found that the complexity of the languages used by the different species of fungi appeared to differ, with the split gill fungus (Schizophyllum commune) using the most complicated lexicon of those tested. This raises the possibility that fungi have their own electrical language to share specific information about food and other resources nearby, or potential sources of danger and damage, between themselves or even with more distantly connected partners.
Adamatzky's findings suggest that fungi might use "words" to form "sentences" to communicate with neighbours. However, it is important to note that some scientists are skeptical of these findings and believe that more research is needed before accepting electrical impulses in fungi as a form of language.

The complexity of fungal languages
Mushrooms and other fungi have long been considered inanimate and silent organisms. However, recent research suggests that this ancient kingdom of organisms may have an electrical "language" of its own. This language is transmitted through thread-like filaments called hyphae, which form a thin web called a mycelium that links fungal colonies within the soil. These networks bear a striking resemblance to animal nervous systems.
The "language" of fungi consists of distinctive patterns of electrical impulses, similar to the spikes of electrical potential that comprise the "language" of the nervous system in animals. By measuring the frequency and intensity of these impulses, researchers have found that they cluster into patterns resembling vocabularies of up to 50 "words", with the split gill fungus (Schizophyllum commune) exhibiting the most complex "sentences". These patterns of electrical activity may be a means for fungi to maintain their integrity or to communicate about newly discovered sources of food or potential dangers in their environment.
While the idea of fungal language is intriguing, it is important to note that not all scientists are convinced. Some would like to see more evidence before accepting these electrical impulses as a true form of language. Additionally, it is worth considering that the definition of "language" itself is complex and multifaceted, encompassing not only spoken and written communication but also sign languages, dance genres, and even musical expressions.
In conclusion, the potential existence of a fungal language underscores the complexity and sophistication of these organisms. While the electrical impulses detected in fungi may not constitute a language in the traditional sense, they highlight the intricate communication networks that enable fungi to interact with their environment and other organisms. As research in this field progresses, we may gain a deeper understanding of the hidden languages used by organisms across the kingdoms of life.

Fungi's ability to feel pain
Mushrooms do not have a nervous system and, therefore, are not able to feel pain. They are about as conscious as plants. Mushrooms do not show any signs of distress when they are plucked from the ground, chopped up, or eaten. However, it is important to note that the mushroom is just the fruiting portion of a network of mycelium that lives underground. The mycelium is a thin web of thread-like filaments called hyphae that links fungal colonies within the soil. These filaments react to their environment, pursuing food, and recognizing threats.
Recent research has found that mushrooms may use a form of language to communicate with each other. This language consists of electrical impulses transmitted across the mycelium, which are similar to the patterns of electrical impulses in animal nervous systems. The complexity of the languages used by different species of fungi appears to differ, with the split gill fungus (Schizophyllum commune) using the most complicated lexicon of those tested. This raises the possibility that fungi use this electrical language to share specific information about food, resources, and potential dangers with other fungi or distant partners.
Fungi's ability to transmit information and react to their environment has led to the concept of "minimal selfhood," which is a pattern of conscious behavior that does not require an organism to possess a brain or neural tissue. Minimal selfhood is based on three intrinsically reflective activities: self-maintenance, self-reproduction, and self-containment. An organism with minimal selfhood can direct energy to maintain its processes and reproduce, and it is defined by a physical boundary.
While fungi do not have a nervous system and cannot feel pain, their ability to communicate, react to their environment, and exhibit minimal selfhood shows that they are more complex and interactive than previously thought.

Similarities between fungi and animal nervous systems
Mushrooms and fungi are neuronless organisms, meaning they do not possess a nervous system. However, recent research has revealed that they transmit information using electrical impulses across thread-like filaments called hyphae. These filaments form a thin web called a mycelium that connects fungal colonies in the soil. This network bears a striking resemblance to animal nervous systems, suggesting that fungi may have their own form of language to communicate with neighbouring colonies.
The study of fungal behaviour and cognition is a relatively new field, and scientists are still working to understand how these neuronless organisms function. Despite lacking a nervous system, fungi exhibit complex behaviours, such as pursuing food sources and recognizing threats. This has led to the concept of minimal selfhood, which describes an organism's ability to maintain its processes, reproduce, and define itself by a physical boundary without possessing a brain or neural tissue.
Fungi, such as mycorrhizal fungi, form intricate partnerships with plant roots, connecting neighbouring plants and providing them with nutrients and moisture. This symbiotic relationship highlights the sophisticated capabilities of fungi despite their lack of a nervous system.
Furthermore, phylogenetic studies have revealed that animals and fungi are closely related, sharing a monophyletic group known as Opisthokonta. This suggests that the genomic features characteristic of animals and fungi may have arisen before the divergence of these two kingdoms. The discovery of these shared evolutionary traits provides valuable insights into the ancient kinship between animals and fungi.
In conclusion, while mushrooms and fungi lack a nervous system, their ability to transmit information via electrical impulses and form complex networks resembles the language and communication systems observed in animals. The study of fungal cognition expands our understanding of consciousness and intelligence beyond traditional brain-centred definitions, inviting a broader perspective that encompasses the unique characteristics of diverse organisms.
