My latest creation. Six trading cards, each 3×5″ that depict the science of pain. These were all done with colored pencil. Notice the heavy use of red and orange-to depict pain and also my favorite colors. Opioid Epidemic shows the mu-opioid receptor, a seven transmembrane G-coupled receptor that promotes the actions of opioid molecules like morphine, hydroxycodone, and heroine. I also show the chemical structure for morphine. Pain Neuron Circuits shows interconnections between neurons in the central nervous system which are responsible for transmitting painful information to the cortex for perception of pain. Neuron just shows the axon and dendrites of a neuron in the central nervous system that would transmit painful stimuli. Axons shows a group of axons that would be found in a peripheral nerve and transmit signals from painful stimuli from the site of injury or simulation to the central nervous system. Pain Synapse shows the transmission f nociceptive stimuli through synapses in the central nervous system. The axon terminal, in red, has vesicles that contain excitatory chemical (neurotransmitters) that diffuse across a synapse to the other side to send their signals. These chemical signals are turned into electrical signals and transmitted as action potentials to the next synapse. Pain Action Potential shows how an electrical current that sends the signals. Ion channels that use sodium (Na+) are responsible for the initial upward phase of the action potential, and potassium and chloride are responsible for the downward phase of the action potential. I am submitting these to Art Science Gallery in Austin, TX for a open call for science trading cards – https://www.artsciencegallery.com. If you live in Austin go see the show of the sciart trading cards: Exhibition Dates December 2 – 24, 2017. Maybe I will get lucky enough to have them displayed.
