This enabled them to detect the activity of mouse neurons from repeated stimulation of their whisker pads. Using this modification - and a powerful MRI scanner - the researchers could track brain activity on the millisecond timescale, a temporal precision much greater that of conventional fMRI. Instead, Park and his team at Sungkyunkwan University in Seoul tweaked the software to capture brain image data in segments, then used a computer algorithm to reconstruct the image. Typically, fMRI acquires brain slices as complete images - a process that limits how quickly the method can gather data. To reveal how the brain works, he thought, fMRI had to become much faster. But these blood-flow-related - or haemodynamic - changes are relatively slow compared with the neurons that they represent. The technique works by picking up on changes in blood oxygen levels, which fluctuate with neuronal activity. He found himself in seminars where researchers described studies of the human brain they had conducted with fMRI. While conducting his PhD in medical physics, Park had developed a fascination for neuroscience. Jang-Yeon Park, an author of the study, had been pondering the limitations of fMRI since his graduate student days at the University of Minnesota in Minneapolis. Researchers in South Korea seemed to have overcome one of the biggest limitations of functional magnetic resonance imaging (fMRI), a popular method for studying the human brain 1.
