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…
We are trying to understand what causes bipolar disorder and how medications treat bipolar depression. Particularly, we are looking at the importance of dopamine signaling in the process. If you participate, you will have two different brain scans (MRI and PET scan). You will also have treatment for your…
We are trying to understand what causes bipolar disorder and how medications treat bipolar depression. If you participate, you will have two different brain scans (MRI and PET scan). You will also have antidepressant treatment for free. We will then be able to see whether information on the brain scans connects with how people…
This is a research study to understand what causes bipolar disorder and how medications treat bipolar depression. Particularly, we are looking at the importance of inflammation in the process. If you participate, you will receive an experimental medication for your depression named ethyl…
We will evaluate the D-cycloserine (DCS) and lurasidone with MRI measurement of brain responses to DCS. DCS is a drug that works on the same brain receptor as ketamine. DCS is not approved by the FDA for bipolar depression. Study participants will receive a dose of lurasidone or placebo in one MRI and a dose of DCS in another…
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 study is a double-blind and placebo-controlled study to assess its efficacy of the new drug Lumateperone for patients with Major Depressive Episodes associated with Bipolar I and Bipolar II disorder. Lumateperone is thought to exert its antidepressant effect through interaction with sereotogenic, dopaminergic, and glutamergic neurotransmitter targets.…
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…
The goal of this study is to examine how effective and well-tolerated a possible new treatment for individuals who injure themselves frequently will be. All research procedures can be done from home no in-person visits are required. We are studying a minimal-risk form of electrical brain stimulation called transcranial direct current stimulation, or tDCS.…
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,…
