That First Kiss May Physically Change Your Brain

Written by 

Over the course of a lifetime, a person has a handful of life-changing moments, including memorable events like a first kiss, relationship endings, and deaths. While you may think about those moments for the rest of your life, though, you probably assume your brain doesn’t experience physical changes as a result.

A new study reveals that the brain actually does undergo alterations as a result of those events. Rockefeller scientist Charles D. Gilbert studied perceptual learning, which is the process of honing your brain to better perceive even the most subtle sights, sounds, and smells. Over time, people become better able to make those perceptions, even though they don’t even realize it. Gilbert wanted to study if the brain could remodel itself in response to life events.

His research, which was published in the Proceedings of the National Academy of Sciences, studied how the brains of two macaque monkeys responded as they worked to improve on a series of tasks. As the monkeys improved, the team noticed that the neurons in their visual cortex actually shed old axons and grew new ones. Based on these results, they concluded that they believe the circuitry of the human brain is constantly changing—a quality called plasticity. It supports a long-held theory that the human brain doesn’t stop developing after childhood.
