Studies of Blood Flow to the Brain During Thought Clinical Trials Facts presented on Clinical Trials Search isn't designed to be a substitute for proven healthcare advice, calls or treatment by using a genuine medical doctor. We aren't mDs. Always confer with your doctor on Studies of Blood Flow to the Brain During Thought conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Studies of Blood Flow to the Brain During Thought Clinical research trials and Studies of Blood Flow to the Brain During Thought healthcare trials occur in a lot of of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectivity of new does drugs. The role of the studies / undertakings is to solve specific human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector companies to find treatments for all kinds of conditions, including Studies of Blood Flow to the Brain During Thought. Studies of Blood Flow to the Brain During Thought Clinical Trials and other clinical trials allow for volunteers to access health treatment choices before they are available to the general public. Many times the test subjects get treatment for without cost, and sometimes they are compensated for their time. Occasionally there is a cost for a Studies of Blood Flow to the Brain During Thought clinical trial. Test subjects typically receive the most effective healthcare possible for their Studies of Blood Flow to the Brain During Thought condition. Risks are a reality, nonetheless, and could include extra or frequent dr. calls, health hazards (perhaps life-jeopardizing), and/or the treatment being ineffective. Trials are federally regulated with rigid guidelines to protect clinical trials subjects.

Studies of Blood Flow to the Brain During Thought
For Condition: Cognition Disorder,Healthy
Status: Recruiting
Sponsor(s): National Institute of Mental Health (NIMH) ,
Synopsis: The purpose of this study is to use brain imaging technology to measure changes in blood flow to areas in the brain as individuals perform intellectual tasks. This study will use functional magnetic resonance imaging (fMRI) to examine blood flow to areas of the brain as participants engage in tasks associated with visual perception, visual recognition, and memory.
Details: Magnetic resonance imaging will be used to measure hemodynamic changes in healthy human subjects engaged in performing cognitive tasks. Specific questions concerning the location of the neural systems that mediate perceptual and semantic representations of objects and the spatial coordinate systems used for object localization will be addressed.
Eligibility:
Study Type: Observational, Natural History
Minimum Age/Maximum Age: /
Genders: Both
Protocol Entry Criteria: INCLUSION CRITERIA: Healthy adults, ages 20-65 All subjects will be given a medical and neurological examination. A full medical history will be obtained.
