Are glutamate and lactate increases ubiquitous to physiological activation? A 1H functional MR spectroscopy study during motor activation in human brain at 7 Tesla

B Schaller, L Xin, K O'Brien, AW Magill, R Gruetter - Neuroimage, 2014 - Elsevier
Recent studies at high field (7 Tesla) have reported small metabolite changes, in particular
lactate and glutamate (below 0.3 μmol/g) during visual stimulation. These studies have been …

SA2RAGE: A new sequence for fast B1+‐mapping
