MRSI is used to measure the metabolite concentrations along medial wall that consisting most of brain regions in default mode network (DMN). This study found that NAA and Cre show higher baseline levels in DMN regions covering part of prefrontal cortex and posterior cingulate cortex than in non DMN regions. This preliminary finding suggest that active neuronal activity of DMN may result in higher baseline metabolite levels.
