Cracking a century old mystery based on potassium channel origami windmill model: Golgi staining method for 1% to 5% neuronal staining mechanism

Abstract The phenomenon of only 1% to 5% neuronal staining using the Golgi staining method, a technique related to the 1906 Nobel Prize in Physiology or Medicine, has plagued the neuroscience community for a hundred years. This article is based on the original “potassium channel origami windmill model”, combined with ion diameter matching, chemical reaction mechanism, and experimental time window verification, to reveal the core mechanism: in living neurons, the inverted conical “origami windmill” structure composed of DNA tetramers is driven by cations to rotate the windmill, adjust the central pore closure of the tetramer enclosure, and block the infiltration of silver ions; After cell death, the "windmill" falls off, causing the channel to open. Silver ions (126 pm) and compounds infiltrate with water molecules (27 pm) and are reduced to black elemental silver; The staining rate of 1% to 5% is determined by the asynchrony of cell death and the 24 ~ 72 hour experimental preservation window. This mechanism achieves cross scale correlation between microstructure and macroscopic staining phenomena for the first time, solving a century old technological puzzle and providing new ideas for interdisciplinary research in neuroscience.
