How similar could the mycorrhizal network really be to a neural network? Sure, the pattern of the network and the molecules transmitting from node to node through the links might be similar. But what about the existence of the synapse; isn’t that crucial to signaling in a neural network? This could also be important in a tree detecting whether its neighbors were stressed or healthy. Just as neurotransmitters pass signals across the synaptic cleft from one neuron to another in our brains, signals might also diffuse across a synapse between interfacing fungal and plant membranes in a mycorrhiza.
