maze

The second test used a maze set up in a tank of murky water.

Bad Hair is designed in that way, where you’re put through these experiences, and only when you get to the end of it, you realize you’ve been in a maze the whole time.

In other experiments, he trained planaria to run through mazes and even developed a technique for extracting RNA from trained worms in order to inject it into untrained worms in an effort to transmit memories from one animal to another.

The ripples weren’t random—rather, they recapitulated in time and space the same neural activity the team observed earlier, while the mice were learning to navigate a new maze.
