We are conducting a study on depression and suicide risk, and participants can earn up to $300 for taking part. Suicide rates in the U.S. are rising, and new treatments are urgently needed. This study focuses on the brain chemical glutamate, which may play an important role in mood and mental health. We will compare glutamate…
The purpose of this study is to use Positron Emission Tomography (PET) to identify changes in brain chemistry that may cause an episode of depression. This study will be carried out in approximately 30 subjects. PET is a technique that provides "pictures" of chemical connections in the brain by injecting and monitoring a…
The Davachi Lab is currently running research studies to investigate information processing. These behavioral studies may involve looking at negative, neutral, and positive images on a computer screen (such as objects, faces, or scenes) and/or listening to negative, neutral, and positive auditory sounds (such as tones with varied pitches or human-produced…
This research study uses non-invasive brain imaging called functional near-infrared spectroscopy (fNIRS). For fNIRS, a small infrared bulb shines light through the skull, and a special light detector is able to measure oxygen use in the brain. Our goal is to understand oxygen use by brain mitochondria cells in major depression…
This research study uses MRI scans to compare the effect of two medications on suicidal thoughts and brain activity in people who have opioid use disorder. We hope to develop a better understanding of how well these two medications help depression and suicidal thoughts. You may qualify if you have opioid use disorder and…
The Davachi Lab is currently running research studies to investigate information processing. These behavioral studies may involve looking at neutral images on a computer screen (such as objects, faces, or scenes) and/or listening to neutral auditory sounds (such as natural ambiance or artificial tones), and making judgments about them. In this study,…
