Scientists look to build computers from brain cells grown in lab
A new field of research dubbed"organoid intelligence" is emerging as scientists look to build computers from lumps of brain cells grown in a petri dish.
AI can now outperform humans at multiple tasks, but humans are still much better at processing information and learning new things, academics who coined the term"organoid intelligence" argued in aDeepMind's AlphaGo system beat the world's best player at a competition in 2016, but required intensive training on samples generated from hundreds of thousands of games.
Researchers believe some of the brain's computational abilities and power could be replicated in organoids. Unlike traditional computers, these brain cells can't be programmed using software. Instead, their electronic signals have to be manipulated somehow and used to control an output device. Smirnova believes organoids can be manipulated through electrode arrays where input signals can influence output signals. These jumbled mass of cells could, in theory, be trained to carry out simple tasks."The electrical signals exchanged between brain cells can be recorded by electrodes in contact with the organoid.
