Scientists Build a Living AI Device Using Real Brain Cells

Princeton researchers built a 3D biocomputing device that combines living neurons with embedded electrodes and wires.

The mesh supports about 70,000 neurons and can record, stimulate, and learn electrical patterns over months of testing.

The work points to new brain-computer hardware that could help explain neural networks and inspire far more energy-efficient AI.

The study was published in Nature Electronics and involved Princeton University researchers including Tian-Ming Fu, James Sturm, and Kumar Mritunjay.
