What do mushrooms have in common with the human brain, the internet, or a city? I will explore the underworld of fungi and how these organisms solve problems, shape their environment, and adapt to change. I am curious about the displays of "intelligence" that emerge from mycelial networks and what they share with other complex systems such as communities of social insects or human societies. Hopefully, my project can provide insight into the way human beings understand themselves and their mind as a part of larger entities, including nature.
