Forest-sized brains

A couple of years ago I wrote in the abstract about ‘Slow thoughts from a planet sized brain‘ [on March 25th, 2020].  I read on vacation in Suzanne Simard‘s book, ‘Finding the Mother Tree‘ that glutamate, which is the most abundant neurotransmitter in the human brain, is also transmitted through mycorrhizal networks connecting trees in forests. Mycorrhizal fungi live in the soil around the roots of plants in a symbiotic relationship with the plants transmitting water to, and receiving sugar from, the plant roots.  Fir trees have been shown to transmit information about threats, e.g., budworm infestations, to one another and to other species of tree.  The speed of this information transmission is fast enough that production of enzymes to protect the trees increases within a day of the appearance of the threat.  We have assumed that folklore tales about enchanted forests are products of our imagination; but perhaps they are based on a long-lost appreciation that forests possess a level of consciousness.  Consciousness seems to require different parts of a system to communicate with one another and form networks [see ‘Digital hive mind‘ on November 30th, 2016], which Simard and others have demonstrated occurs in forests with the mycorrhizal networks being equivalent to the neural network in our brains.  The scale of a forest’s network is such that communication will be slower than in our brain but that is not necessarily an inhibitor of consciousness.  So, perhaps forest-sized brains would be intermediate between human-sized and planet-sized.

    Robert Graves in his brilliant The White Goddess says mythology is based squarely on seasonal observation of life in the fields – and tree-lore. I’ve always felt that “lore” is attached to a very wide brief …..
