Your Brain on Social Media
So our brains are wired to process social signals. What then happens to our brains on social media?
Neuroscientists at UCLA wanted to know, so they created an Instagram-style app to study how the brain reacts when we scroll through photos in our Instagram feed. The app displayed a series of photos in a row, just like on Instagram. The researchers then studied adolescents using fMRI machines and recorded which regions of their brains lit up as they used the researchers’ version of Instagram. They also experimentally manipulated the number of likes a photo got as well as what types of photos the participants saw, including whether they saw their own photos or others’ photos and whether the photos depicted risky behaviors (like drinking alcohol) or neutral behaviors. They’ve since corroborated their results in young adults and for giving as well as receiving likes. As
