What Harry Potter Can Teach Us About Neuroscience

When reading about Harry Potter’s adventures fighting Lord Voldemort or flying around the Quidditch field on his broomstick, we can become so absorbed in the story that the characters and events start to feel real. And according to neuroscientists, there’s a good reason for this.

Researchers in the Machine Learning Department at Carnegie Mellon University scanned the brains of Harry Potter readers, and found that reading about Harry’s adventures activates the same brain regions used to perceive people’s intentions and actions in the real world.

The researchers performed fMRI scans on a group of eight study participants while they read chapter nine of Harry Potter and the Sorcerer’s Stone, which describes Harry’s first flying lesson. Then, they analyzed the scans, one cubic millimeter at a time, for four-word segments of the chapter in order to build the first integrated computational model of reading. The researchers created a technique such that for each two-second fMRI scan, the readers would see four words. And for each word, the researchers identified 195 detailed features that the brain would process. Then, an algorithm was applied to analyze the activation of each millimeter of the brain for each two-second scan, associating —> Read More Here
