Indian scientist builds mini 'brain' inside 3D chip that can learn from signals

IIT Kharagpur alumnus Kumar Mritunjay and his team have developed a device where lab-grown brain cells grow and communicate inside a 3D electronic scaffold. The system can be observed over long periods, allowing scientists to study how neural connections evolve. It can also be stimulated to mimic learning, paving the way for new treatments for neurological diseases and AI advances.
