Scientists recreated what mice saw from brain activity alone

Researchers from UCL reconstructed 10-second video clips that mice watched using only recordings of individual neuron activity in the visual cortex. The work is published in eLife and could help understand how the brain transforms visual signals into an internal picture of the world.

• Reconstruction based on individual neuron activity, not fMRI
• Accuracy increased with more recorded neurons
• System recreated a 10-second video not in training data
• Method uses a neural coding model from the Sensorium 2023 competition
