The Exponential Distance Rule Accurately Predicts the Topology and Functional Properties of the Drosophila Connectome
The exponential distance rule, which states that the probability of axons decreases exponentially with their length, accurately describes the structural brain network of the Drosophila fruit fly. A one-parameter model based on this rule effectively captures numerous binary and weighted properties of the Drosophila connectome, revealing that geometric constraints play a key role in shaping brain networks across species.
