Scientists observe neural activity in lab-grown mini-BRAINS

Scientists in Japan have created mini-brains with functional neural networks. These so-called mini brains, known more formally as cerebral organoids, may not be conscious, but their use in the lab could provide key insight to the processes by which information is encoded, scientists say. The organoids are essentially a simplified version of the human brain which have been grown artificially using 3D tissue cultures. Scientists in Japan have created mini-brains with functional neural networks. They lack more supporting structures such as blood vessels and the surrounding tissues, and cannot'think.'
