ClinConnect Summary

This clinical trial is studying how a specific brain signal, called the aperiodic signal, affects working memory (WM), which is our ability to hold and use information in our minds without any outside help. Previous research has shown that certain brain activities are linked to how well we can use our working memory, but it’s not clear which signals are the most important. The goal of this study is to better understand the role of the aperiodic signal in helping with tasks that require working memory.

If you are between 18 and 35 years old, can see normally (or with glasses), and can understand English, you might be eligible to participate. However, people with certain conditions like ADHD, neurological disorders, or previous brain surgeries are not eligible. Participants will be asked to complete specific tasks while their brain activity is monitored. It’s important to know that this study is still recruiting participants, and those who join will need to commit to all study procedures. Your involvement could help researchers learn more about how the brain works and improve understanding of memory function.
