This project seeks to identify causal neural mechanisms underlying unwanted, repetitive behaviors (compulsions). Using non-invasive brain stimulation coupled with practice in a computer task, we will modulate activity in a target brain region and measure effects on compulsive behaviors and related measures. This work could ultimately lead to the ability to treat compulsions more effectively by targeting the regions of the brain that can help or hinder attempts to overcome compulsions.
The goal of this study is to find out if brain stimulation can help people stop skin-picking or nail-biting. The study wants to answer two main questions: 1. Does brain stimulation reduce the urge to pick skin or bite nails after those urges are triggered? 2. Does brain stimulation reduce how often people pick their skin or bite their nails? Participants will: * Talk about their skin-picking, nail-biting, and other mental health concerns * Be placed in situations that make them want to pick or bite * Rate how strong their urges are before and after brain stimulation Researchers will compare real brain stimulation to a placebo (a fake version that looks the same but has no effect) to see if the real stimulation works to reduce skin-picking and nail-biting urges and behaviors.
The overall goal of this project is to determine whether a new form of family-based treatment for repetitive and inflexible behaviors, delivered using videoconferencing technology, can counter any negative effects of those behaviors, but also improve positive outcomes for young children with ASD.
