This is a poem I wrote about how the brain structures its own neural connectivity in order to produce metaphors, poetry, analogies, allegory, and the like, including through its use of semaphorin guidance molecules and such. So one can think of it as a type of meta-poetry I suppose.
“Meta-phorin”
Branches born from distant gardens
Fed by the fruits of senses streamed
Spreading out, a vibrant pattern
Crawling along those ancient trees
Toward the scents, hypnotic dance
Winding paths until they meet
Their tips begin to touch at last
Caressing as they’re intertwined
Hebbian journey, webs of gnosis
Embodied frames are now sublime
Synaptic waters flowing faster
Emotions growing, bearing passion
Creative means no longer foreign
By the meta-semaphorin
The Open Mind 
Brain poetry!
Excellent idea and nicely written too!
Thanks for the compliment! I’ve written a couple poems that are related to the brain, cognition, and the like, as they are an interest of mine. I love to dabble! One poem that talks about the brain in relation to knowledge, our subjective experience, perception, and some cognitive biases, is “The Bounds of Subjectivity”. I really liked writing that one!
