ClinConnect Summary

This clinical trial, titled "Decoding and Modulating Affective Brain States," is exploring ways to help individuals who struggle with feelings of sadness, worry, and negative thoughts, particularly those with major depressive disorder and anxiety. The researchers aim to create personalized maps of how negative emotions affect the brain. They will use advanced imaging techniques (like fMRI, which is a type of brain scan) and muscle activity data to understand each participant's unique emotional patterns. Participants will then receive targeted brain stimulation over several sessions, which may help lessen these negative feelings.

To join the study, participants need to be between 18 and 65 years old, right-handed, and have a score of 10 or higher on a depression questionnaire. They should be able to understand instructions in English and consent to participate. However, those with certain psychiatric or neurological conditions, recent use of certain medications, or who cannot undergo an MRI will not be eligible. Throughout the study, participants can expect to engage in brain scans and receive stimulation designed to improve their emotional well-being.
