Anyone can see and download the data, and there are papers both available and on the way detailing the work. The brain map won’t accomplish much by itself. However, it could prove to be a treasure trove of data for scientists looking to understand fruit flies in particular or brain functionality at large.

With that said, it’s important to temper expectations. Even as large as this map is, it represents just a quarter of the 100,000 neurons in a typical fruit fly. Most larger species’ brains are considerably more complex, and a human’s 86 billion neurons would take much, much more work to map correctly. This is an important moment, but it’s ultimately a stepping stone.

Scientists already knew that humans have specific areas of the brain used to recognize faces, words, numbers and even celebrities like Jennifer Aniston, Bill Clinton and Kobe Bryant. Those areas of the brain are often in the same place for large groups of people. A recent study by Harvard Medical School found that for monkeys to develop similar regions, they need to be exposed to objects from a young age. The researchers at Stanford wondered if the same were true in humans. Pokémon fans proved to be perfect subjects, as most began playing when they were quite young and because the characters are so unique.

The findings support theories that early childhood exposure is necessary for developing dedicated brain regions, and that from an early age, our brains change in response to experiential learning. Because the fold activated by characters like Pikachu, Wobbuffet and Bulbasaur is the same fold that responds to images of animals, the researchers also believe there’s some kind of underlying constraints hardwired into the brain that determine how those changes happen.

Now, as you watch the long-awaited Detective Pickachu movie coming out later this week, you might wonder if you have a dedicated brain fold actively identifying the characters. You might also wonder how other games you obsessed with as a kid have found their way into the structure of your brain.
