Human Brain Tissue Powers Computer

Brainoware was created by taking these brain organoids and connecting them to an array of high-density microelectrodes through an artificial neural network known as reservoir computing. Guo and crew used stimulation to transport information into the organoid, where the reservoir wherein that information is processed. After processing the information, Brainoware spits out its calculations in the form of neural activity.

The input and output layers of the new brain-computer come from regular computer hardware. Guo trained the layers to play nice with the organoid, using the output layer to read the neural data and make classifications or predictions based on the input. To test their system, the researchers provided Brainoware with 240 audio clips, each featuring a different male speaker saying Japanese vowels.
