MRS Measurement of Glutamate and GABA Metabolism in Brain
Conditions: Normal Physiology
Sex: All
Ages: 18 Years – 65 Years
Healthy volunteers: Yes
Phase: NA
Enrollment: 200
Sponsor: National Institute of Mental Health (NIMH)
Location: National Institutes of Health Clinical Center Bethesda Maryland
Summary
This study will use magnetic resonance spectroscopy (MRS) to measure in the brain the transfer of \[13\]C as it is naturally metabolized from glucose to specific chemical transmitters. From this method, we can measure the rate of production of an important excitatory neurotransmitter (glutamate) as well as an inhibitory neurotransmitter (GABA)....
