  "account": "Neuroscience suggests the existence of a canonical microcircuit that underpins cortical computation across various brain systems. In the field of artificial intelligence, neural networks have emerged as a universal computational substrate. Researchers have now utilized large-scale data and advanced mapping techniques to compare neural network motifs with the brain. To achieve this, they embedded a range of candidate microcircuit architectures within a common spatial macrocircuit, and measured their alignment with a comprehensive set of cortical signatures.\n\nThe findings reveal that a particular circuit type, the transformer, stands out in its ability to capture fine-grained unit-level circuit details, population-level functional maps, and neuronal activity patterns. Additionally, the transformer exhibits systems-level wiring efficiency and aligns with behavioral demands. The critical factor enabling the transformer's success is a learned multiplicative component that makes relational information available without the need for extensive long-range wiring.\n\nThese results indicate a striking convergence between computational motifs found in natural neural circuits and those employed in artificial intelligence.",
