A fruit fly connectome with 166,700 neurons and 25.6 million connections was integrated into a 1.2 billion parameter frozen language model, training only 278,528 additional parameters. The connectome integration achieved 0.0222 nat per token improvement, but control models without the biological wiring performed slightly better across all random seeds.
