No body, no dopamine, no problem. Scientists have successfully coached lab-grown brain tissue to solve a classic robotics challenge, proving that the will to learn is hardwired into our neurons.

Scientists trained a brain organoid to solve a well-known engineering task, and its success demonstrates the increasing complexity of lab-grown brains.

Study authors Hunter Schweiger (left) and Ash Robbins. Imagine balancing a ruler vertically in the palm of your hand: you have to constantly pay attention to the angle of the ruler and make many small ...

At top, a neural spike is read out and decoded to move the cart. On the bottom, a waveform indicates electrical stimulation into specific neurons to encode the pole's angle into the organoid. This ...
