At the back of your eyeballs is a pad called a Fovia. It is made of rods and cones. The rods are a bunch of photon receptor-pancakes stacked into a rod shape designed to detect light photons but only at a certain wavelength band for red and green, and for tetrachomats: y. When a photon comes in, there is a Rhodopsin molecule that gets blown apart, and this blown-apartness is sampled by other atoms in an analog signal processing system that is amplified up and converted into data packages that key for lines, shapes, and primitive template-patterns defined by the Fovia sent down the optic nerve to the visual cortex at the back of your head. The Fovea has to reconstruct this Rhodopsin, so it can detect another photon. This is where 1,3,7 Trimethylxanthine comes in. Coffee was evolved by plants taking control of humans to be their be "fight or flighting" aggressive seed distribution system, and so this system releases adrenaline, which then speeds up the Rhodopsin reconstruction process, giving you the mysterious feeling that the physics textbook suddenly is fun and exciting. Then you notice everything makes sense, the textbooks are hitting short term and long term memory a lot easier. This "speed up" principle happens across the tens of thousands of systems, including the stomach lining and digestive system which has similar touch and go feedback loops amplified or inhibited by these neurotransmitter imposters.
