Mini-brains grown from stem cells recognized Braille letters: three organoids together reached 83% accuracy

Living neural tissue passed on a distinguishable signal for computation — an early step toward biohybrid computers.
Researchers at the University of Bristol (Tianyi Liu and Benjamin Ward-Cherrier) fed human brain organoids (about 10,000 neurons each) electrical signals converted from data from a tactile sensor reading Braille letters. A classifier determined the letter from neuron activity: one organoid with about 61% accuracy, three together with 83%. In Frontiers in Artificial Intelligence the authors note that they did not demonstrate learning or long-term changes in the organoids, and tested only one task with a fixed signal encoding.
