My Neuron (an original sonnet)

If I should think of all things in the world,
A tiny neuron in my brain is you.
Your axon weaves throughout my cortex, twirled—
About my thalamus your dendrites grew.
When not around, chloride ions invade
And inhibit my action potential,
Obstructing second-messenger cascade
And making sodium less substantial.
Occipital lobe neural synapses
Fire when you enter my field of view—
My nervous system instead collapses
As neurites shrug and declare, “I am through.”

For when you're here my whole body goes numb—
My brain can't function—I am so very dumb.
