Researchers at Princeton University have developed a 3D bioelectronic device that merges living brain cells with advanced embedded electronics to create a neural network capable of computational tasks. The device features a 3D mesh design with living tissue that can differentiate patterns using computational techniques. Unlike previous methods using brain cells for computation, this device allows for recording and stimulating neurons' electrical activity at a finer scale. The team successfully trained the device to identify recurring pulse patterns and differentiate between distinct patterns, aiming to scale it for more complex tasks. This technology not only delves into brain computing secrets but also holds potential for understanding and treating neurological diseases while addressing AI's energy consumption challenges.
