MONKEYMIND MACACA MULATTAANATOMICAL SPECIMEN · RHESUS MACAQUE
SUBJECT ALPHA
Macaca mulatta, male, 6 y 2 m, 7.1 kg. A human cortical graft in the right orbitofrontal cortex and a human MCPH1 transgene. Two 96 channel arrays: one in area 13, where the brain prices things, one in area 7a. Paid in juice, 0.2 ml a unit.

THE CHIMERA · TAN ET AL., CELL 2021 · SHI ET AL., NSR 2019
What happens when a human brain is combined with a monkey?
In 2021 human stem cells were put into 132 monkey embryos. They did not die. They spread, signalled to the monkey cells around them, and three embryos were still growing with human cells inside on day 19, when the experiment was stopped on purpose.
In 2019 a lab in Kunming gave rhesus macaques a human copy of MCPH1, a gene that sets the pace of brain development. Their brains matured on a slower, more human schedule and they did better on short term memory. Subject Alpha is what you get if you take both results seriously.
Both papers, the four epochs from blastocyst to order book and the monkey versus human table are in the docs.
FIELD NOTES · THREE INDEPENDENT READS
Context, not claims
Reporting from the institutions and science desks behind the three ideas this project joins: primate markets, human–monkey chimeras and cellular brain maps.
Humans’ rational and irrational buying behavior is mirrored in monkeys
Capuchins spent token budgets, responded to changing prices and preferred a possible gain over an equivalent possible loss—the behavioral basis for the desk.
Source institution ↗International team creates first chimeric human-monkey embryos
A careful account of the Tan et al. experiment, what the researchers actually made, why they made it and the ethical questions the work raises.
Reported context ↗New “atlas” of a monkey brain maps 4.2 million cells
An accessible look at the scale of modern macaque brain mapping and the cell-level atlas behind the specimen, slice and connectome language.

THE TRADING DESK · ROBINHOOD CHAIN
Monkeys, trading
In 2005 Yale taught seven capuchins that a silver disc bought food. Once it stuck they shopped like anyone: bought more when the price dropped, hated a loss more than they liked a gain. MonkeyMind does the same with tokens. The array reads Subject Alpha's value signal every 200 ms, a decoder turns it into buy, hold or sell, and the desk fills on Robinhood Chain. Everything below comes off the chain.
How the decoder is fit, what the ledger reads from the chain, the four animals in the room and the whole Yale story: docs.
SETTLEMENT · $MONKEYBRAIN
The spike window is the receipt
THE RECEIPT
Every order carries the hash of the 200 ms spike window that produced it. Replay the window and you get the same order.
THE DESK
Whatever the decoder points at gets bought or sold on Robinhood Chain, and every fill is listed above with its transaction.
THE TOKEN
$MONKEYBRAIN is the desk's own token. Nothing more is claimed for it.
EVERYTHING ELSE
The docs
The papers in full, the four animals, the four epochs, the millisecond cascade, the comparison table, how the decoder is built, how the ledger reads the chain, how the face and the slice are drawn, and what is simulated. With code.
