Neural Correlates of Real World Spatial Navigation in Humans
Recruiting
The purpose of this study is to understand the neural mechanisms that support real world spatial navigation in humans using deep brain recordings and stimulation during virtual reality (VR), augmented reality, and real world memory tasks. We will determine the cognitive (i.e., memory) and behavioral (i.e., body, head, eye position and movement) factors that modulate deep brain activity and the consequent effects of memory-enhancing deep brain stimulation.

Role of Lisinopril in Preventing the Progression of Non-Alcoholic Fatty Liver Disease, RELIEF-NAFLD Study
Recruiting
This phase II trial investigates how well lisinopril may work in preventing the progression of non-alcoholic fatty liver disease (NAFLD). NAFLD is a condition where there is an accumulation of fatty cells in the liver. NAFLD increases a person's risk of developing liver cancer. Liver fibrosis is the common finding of chronic liver diseases leading to reduced liver function. Lisinopril is a medication that is commonly used to treat high blood pressure. Lisinopril may help to decrease liver fibros... Read More

Kaiser Permanente houses over 6,000 physicians in southern California and it is also one of the largest research centers on the state. On its clinical trial division, Kaiser Permanente conducts clinical trials of almost every specialty funded by pharmaceutical companies, government, and foundations.
The Cedars-Sinai Medical Center located in Los Angeles is one of the largest research centers owned and operated by a private hospital in the United States. Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.
There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.
Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.
In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.
Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future. The following lists of trials are broken down by condition, and to find a specific clinical trial in your area click through to clinicaltrials.gov.
