Scientists Map Largest Mouse Brain Network Using Scenes from ‘The Matrix’ and ‘Star Wars

Quick Summary

• Researchers created a 3D map (“connectome”) of a cubic millimeter of mouse brain tissue, containing 200,000 cells and 523 million synaptic connections.
• It is the largest brain connectome to date-three times larger than one of a human brain region and forty times larger than the full fruit fly connectome.
• The study was conducted by the MICrONS consortium with more than 150 researchers from multiple U.S. institutions.
• Using live imaging on genetically modified mice watching videos like The Matrix or Mad max, combined with electron microscopy and machine learning algorithms, scientists traced cell shapes, synapses, and interaction networks in the visual cortex portion of the mouse’s occipital lobe.
• The dataset reveals specific inhibitory neuron-targeting mechanisms and neural connectivity patterns over long distances in addition to local wiring principles like “fire together wire together.”
• Despite some missing data requiring manual proofreading, the team released findings publicly to advance ongoing neuroscience research aimed at neurological disorders like Alzheimer’s or multiple sclerosis.
• Future work aims for an entire mouse-brain connectome via NIH’s BRAIN Initiative; however, funding remains uncertain following congressional budget cuts.
