An ancient memorization strategy might cause lasting changes to the brain

Weird as it might sound, there are competitive rememberers out there who can memorize a deck of cards in seconds or dozens of words in minutes. So, naturally, someone decided to study them. It turns out that practicing their techniques doesn’t just improve your memory — it can also change how your brain works.

There’s been a long-standing debate about whether memory athletes are born with superior memories, or whether their abilities are due to their training regimens. These tend to include an ancient memorization strategy called the method of loci, which involves visualizing important pieces of information placed at key stops along a mental journey. This journey can be an imaginary walk through your house or a local park, or your drive to work. The important thing is that you can mentally move back through it to retrieve the pieces of information you stored. (The ancient Greeks are said to have used it to remember important texts.)
