Summary
10-second video clips were reconstructed from mouse visual-cortex activity alone, letting UCL researchers recreate scenes the animals watched from neural signals recorded during previously unseen footage.
A dynamic encoding model compared predicted neuron activity for a blank screen with actual single-cell calcium-imaging data, then iteratively adjusted pixels until the generated movie matched the brain response.
Pixel-correlation tests showed high-quality reconstructions with only minimal timing differences, and accuracy improved as data from more neurons were added.
The team plans to sharpen resolution and widen visual coverage to probe why the brain’s internal visual representation diverges from the external scene.
