Brainoware Reservoir Computation Of Biological Neural Networks

Reality is rapidly catching up. In this case, macabre living brain organoids are used for computation not unlike head cheese from Starfish (1999) by Peter Watts.

From Nature:

Brain-inspired computing hardware aims to emulate the structure and working principles of the brain and could be used to address current limitations in artificial intelligence technologies. However, brain-inspired silicon chips are still limited in their ability to fully mimic brain function as most examples are built on digital electronic principles. Here we report an artificial intelligence hardware approach that uses adaptive reservoir computation of biological neural networks in a brain organoid.

In this approach—which is termed Brainoware—computation is performed by sending and receiving information from the brain organoid using a high-density multielectrode array. By applying spatiotemporal electrical stimulation, nonlinear dynamics and fading memory properties are achieved, as well as unsupervised learning from training data by reshaping the organoid functional connectivity.

We illustrate the practical potential of this technique by using it for speech recognition and nonlinear equation prediction in a reservoir computing framework.

I have an even older version of this idea. In this terrific tale by Dr. David H. Keller, an elephant's brain directs a steam shovel.
