Lab-Grown Brain Clump Maps a Path to Adaptive Learning
Researchers at UC Santa Cruz trained a mouse-derived brain organoid to balance a simulated pole using electrical stimulation and reinforcement learning, boosting success from 4.5% to about 46% with adaptive coaching, though the gain faded after rests because the organoid lacks body memory. The study suggests cortical tissue may have intrinsic adaptive computation and could aid neurological disease research, while prompting ethical discussions about using lab-grown brain tissue, especially human-derived organoids.
