Study, 2014: "3D GABA imaging...."

The full title of this American/Austrian/English study is "3D GABA imaging with real-time motion correction, shim update and reacquisition of adiabatic spiral MRSI." It looks at a specific way to measure GABA and glutamate "in vivo", which refers to a process taking place in a living organism.

From the abstract:

"Gamma-aminobutyric acid (GABA) and glutamate (Glu) are the major neurotransmitters in the brain. They are crucial for the functioning of healthy brain and their alteration is a major mechanism in the pathophysiology of many neuro-psychiatric disorders. Magnetic resonance spectroscopy (MRS) is the only way to measure GABA and Glu non-invasively in vivo. GABA detection is particularly challenging and requires special MRS techniques."
