Scientists have used living human brain cells to help a computer distinguish Braille letters with up to 83 per cent accuracy, according to new research that also describes how similar 'biohybrid' systems have been used to steer a robot dog in a navigation task.
The study, published on 16 October in Frontiers in Artificial Intelligence, was written by Tianyi Liu, Hemma Philamore and Benjamin Ward-Cherrier at the University of Bristol. It tested whether human forebrain organoids could process tactile information. Organoids are laboratory-grown, three-dimensional tissue models containing neural cells, not miniature brains.
