Baseline GABA concentration and fMRI response.
Coordination between glutamatergic excitatory neurons and gamma-aminobutyric acid (GABA)-ergic inhibitory interneurons is fundamental to the regulation of neuronal firing rates and is believed to have relevance to functional magnetic resonance imaging (fMRI) contrast. While much is known regarding the molecular behavior of excitatory and inhibitory processes, comparatively less is known regarding the role of such processes in explaining variations in fMRI and related hemodynamic imaging metri...Expand abstract
