Lab-grown brain organoids learn to read Braille via robotic sensor, hitting 83% with three organoids

University of Bristol researchers connected lab-grown brain organoids (10,000 neurons each) on multielectrode arrays to a robotic tactile sensor reading Braille. A single organoid decoded letters 61% of the time; three organoids working in parallel reached 83% accuracy, aided by complementary individual variation. The multi-organoid setup also beat a plain ML algorithm under noise. Published in Frontiers in Artificial Intelligence, the work is a step toward energy-efficient biohybrid computing.
