Predicting Future Errors During Skill Performance
NCT06707207
Recruiting
Background: Many tasks people do every day require a series of individual movements. Control over these movements is called motor skills. But even highly skilled people can make mistakes. Researchers have found that they can predict when a person will make a mistake 0.1 second before it happens. Now, they want to find out if they can increase that time up to 1 second-long enough to warn the person and prevent the mistake. Objective: To see if motor skill errors can be detected up to 1 second... Read More

Multi-System Analysis of Opioid Receptor Binding
NCT05528848
Recruiting
This study will enroll up to 60 adults (including 30 females and 30 males) in three cohorts of up to 20 subjects each. In all three groups, \[11C\]carfentanil whole-body PET imaging will be used to examine the central nervous system (CNS) and broader systemic opioid binding in an initial scan session. In the two groups not receiving standard of care medication assisted treatment (MAT) for opioid use disorder (OUD) the effects on \[11C\]carfentanil binding potential of the blockade of opioid bind...

A Study of the Blood Levels of Palovarotene in Participants With Abnormal Liver Function Compared to Healthy Adult Participants After Intake of a Single Dose
NCT06908954
Recruiting
The main aim of this study is to understand how moderate and severe liver impairment (based on the Child-Pugh classification) affects the body's processing of a single dose of 10 mg maximum of palovarotene, compared to healthy participants with normal liver function. The study will also assess the safety and tolerability of the single dose of palovarotene. Participants will be enrolled in stages and divided into three groups based on their liver function: * Group 1: Healthy participants with... Read More

Study of New Magnetic Resonance Imaging Methods of the Brain
NCT00004577
Recruiting
The purpose of this investigation is to develop improved magnetic resonance imaging (MRI) techniques and hardware for studying brain function. MRI is a diagnostic tool that provides information about brain chemistry and physiology. This study will evaluate new MRI methods for monitoring blood flow to regions of the brain in response to simple tasks. The MRI machine used in this study is more powerful than those in most hospitals, permitting a higher visual resolution. Normal healthy volunteers... Read More

tFUS Induced Transient Scotoma for Individual Dosing
NCT06426498
Recruiting
The purposes of this research study is to: 1. Develop a technique of transcranial Focused Ultrasound Stimulation (tFUS) where meaningful effects on the brain can be easily measured. 2. Use this technique to measure threshold for effective tFUS in individuals. 3. Determine whether disruption of conscious visual detection, versus non-conscious visually-guided behavior have different thresholds for disruption with tFUS.

In Vivo Study of THC-induced Immune-genome Changes at Single Cell Solution in HIV-infected Humans
NCT04920539
Recruiting
In this study, the investigators hypothesize that THC alters the immunogenome in a cell type-specific fashion and alters cytokine production via epigenetic regulatory mechanisms and that these alterations differ between HIV-infected and HIV-uninfected host genomes.

Imaging Techniques in MRI
NCT01130545
Recruiting
Background: - Magnetic resonance imaging (MRI) scans must be performed according to specified sets of parameters that provide optimal images of each organ and each area of the body. These scanning parameters are often specific to the institution or organization at which they are employed, and may also depend on the manufacturer of the MRI scanning equipment. Because MRI scanning equipment is always being updated and upgraded, researchers are interested in developing new and optimized scanning p... Read More

A Study to Evaluate Safety, Tolerability, and Immunogenicity of V350A and V350B in Healthy Participants (V350-001).
NCT06655324
Recruiting
Epstein Barr virus (EBV) is a virus which can cause infectious mononucleosis and is associated with certain kinds of cancer and multiple sclerosis. Researchers are looking for new ways to prevent disease related to EBV and have developed a new study vaccine (V350A and V350B). The main goal of this study is to learn about the safety and tolerability of V350A and V350B in healthy adults.
