The MICrONS program (Machine Intelligence from Cortical Networks) is a five-year project run by the United States government through the Intelligence Advanced Research Projects Activity (IARPA) with the goal of reverse engineering one cubic millimeter—spanning many petabytes of volumetric data—of a rodent's brain tissue and use insights from its study to improve machine learning and artificial intelligence by constructing a connectome.[1][2] The program is part of the White House BRAIN Initiative.[1][2]

Teams

The program has set up three independent teams, each of which will take a different approach towards the goal. The teams are led by David Cox of Harvard University, Tai Sing Lee of Carnegie Mellon University;[1][2] and jointly by Andreas Tolias and Xaq Pitkow of the Baylor College of Medicine, Clay Reid of the Allen Institute for Brain Science, and Sebastian Seung of Princeton University.[3]

The Cox team has aimed to build a three-dimensional map of the neural connections within the source tissue block using reconstructions from electron micrographs.[3]

Technology and infrastructure for storing petabyte-scale volumetric data, including a cloud-based database, bossDB,[4] were developed by the Johns Hopkins Applied Physics Lab.[5]

Approach

The part of the brain chosen for the project is part of the visual cortex, chosen as a representative of a task – visual perception – that is easy for animals and human beings to perform, but has turned out to be extremely difficult to emulate with computers.[1][2]

Cox's team is attempting to build a three dimensional mapping of the actual neural connections, based on fine electron micrographs.[2] Lee's team is taking a DNA barcoding approach, in attempt to map the brain circuits by barcode-labelling of each neuron, and cross-synapse barcode connections.[1] Tolias's team is taking a data-driven approach, assuming the brain creates statistical expectations about the world it sees.[2]
