Near Infrared Spectroscopy

One of the major technological breakthroughs in human neuroscience research has been the development of functional magnetic resonance imaging (fMRI). This technique, for the first time allowed us to measure changes in blood oxygen levels (and by extension brain activity) while subjects were performing a specific task. Over the years, this technique has been improved and refined especially in spatial, which can now be as small as 1 mm. While structural MRI has also been developed for rats and mice, fMRI is technically very challenging, mainly because of the risk of movement… Read More
