how human neurons on a chip learned to play doom?

Human neurons on a chip are brain cells that were made tiny and put onto a special kind of computer chip. These brain cells learned to play Doom, a video game, like kids learning how to ride bikes.

Imagine you're playing a game, and every time you make a move, someone tells you if you did well or not. That’s like feedback, the kind of thing that helps you learn. These tiny brain cells got feedback too: when they made good moves in Doom, they were happy; when they made bad moves, they felt confused.

These neurons on a chip used something called neural networks, which are like groups of friends who pass messages to each other. Each time the game changed, like an enemy appeared or you moved forward, the brain cells worked together to figure out what to do next.

It was kind of like learning how to play catch: at first, it's all guesswork, but with every throw and catch, you get better. The neurons got better too, they played Doom faster and smarter each time!
