MRI-based diffusion tensor imaging (DTI) and tractography

If you had to single out one property that gives the brain its status as the most complex object in the universe, it would be its connectivity – the wiring of its roughly 80 billion neurons. It has been an enormous advance, therefore, for scientists to be able to measure connectivity in vivo, noninvasively. This technique is widely used in cognitive neuroscience including, for example, in studying how age-related changes in a particular tract result in long-term memory impairment, or how abnormalities in another tract are associated with psychopathy, and may be implicated in one of the most famous cases in the history of behavioral neurology. (Hint: The name rhymes with “tinnitus page.”) Here, MRI physicist Andrew Alexander explains how it’s done.”
