Fluctuations in brain signals explained: Spontaneous electrical background rhythms in the brain influence fMRI

Until now, brain scans obtained using fMRI – one of the most important imaging methods in use today – have been affected by fluctuations in the brain activity measured which could not be explained. Researchers at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig and the Charité in Berlin have now shown that certain electric background rhythms in the brain, known as Alpha oscillations, alter the fMRI signal obtained with visual stimuli. To do this, they used a new approach in which quickly changing brain activity, which cannot be captured by the scanner, was measured using
