[en] In this work, we propose a simple yet effective solution to the problem of connectome inference in calcium imaging data. The proposed algorithm consists of two steps. First, processing the raw signals to detect neural peak activities. Second, inferring the degree of association between neurons from partial correlation statistics. This paper summarises the methodology that led us to win the Connectomics Challenge, proposes a simplified version of our method, and finally compares our results with respect to other inference methods.
This is the paper that explains the methodology we developed for winning the Connectomics challenge for which the goal was to infer from observed data the wiring diagram from the brain. 144 teams were participating to this challenge.
