AI Decodes Mouse Brain to Reconstruct Movie Clip

Scientists from École Polytechnique Fédérale de Lausanne (EPFL) have developed an AI tool called CEBRA that can interpret a mouse's brain signals in real-time and reconstruct the movie clip it is watching. The machine-learning algorithm was trained to map neural activity to specific frames in videos and predict and reconstruct the movie clip that a mouse is looking at. The researchers measured and recorded the rodents' brain activity using electrode probes inserted into their brains' visual cortex region and optical probes for mice that had been genetically engineered.
