New 3D device computes using living brain cells — bioelectronic device uses 3D electronic mesh design paired with living tissue

Researchers at Princeton University have created a three-dimensional neural network device that combines living brain cells and advanced embedded electronics. According to a recent press release, this 3D bioelectronic computer was programmed to differentiate patterns using computational techniques.

Basically, we are looking at living brain cells performing computational tasks outside the brain, using embedded electronics. This is not the first time scientists have used brain cells to perform computation. In previous attempts, scientists cultivated 2D cultures in petri dishes or 3D clusters, probing and monitoring activity from the outside.
