A wallet keeps its neuron for as long as its class does not change. Moving up hands you a rarer neuron; dropping a class frees it for the next holder. Motor neurons are never handed out — they move the body.
Every hour the full table (rank, wallet, points, balance, sells, neuron) is exported as CSV and its SHA-256 is stored. The current table is always downloadable; the hash of each hour will be written to Solana as a memo so nobody — including us — can rewrite history.
Download the current tableNeurons, types and positions come from MaleCNS v1.0 (HHMI Janelia FlyEM & Google Research, CC BY 4.0): 165,122 traced neurons of the male Drosophila central nervous system, 140,024 of them with a soma position.
