University of Bristol researchers published October 16 in Frontiers in Artificial Intelligence. Human forebrain organoids under 1 mm across with about 10,000 neurons each received electrical patterns from a tactile sensor scanning the 26 Braille letters. A machine-learning classifier read the neural activity. One organoid hit 61% accuracy. Three combined hit 83% and handled added noise better. Open-loop setup only. The organoids got the signals and fired. They were not trained. Senior author Benjamin Ward-Cherrier said the tissue still carried enough information for solid classification. Combining them improved the result. Early step toward energy-efficient biohybrid systems that use real neural tissue.

Scientists connected lab-grown brain tissue to a Braille sensor.
A computer decoded its electrical responses with 83% accuracy using 3 organoids.
The tissue didn't learn to read. But this could be a step toward biohybrid computers.#AI #Science pic.twitter.com/aJRpdP6i3e
