Researcher at McGovern Institute Supercharges Brain Imaging
Neuroscientists eagerly anticipate the day when they can use non-invasive brain imaging to see precisely what the 10 billion neurons are doing throughout a person's brain. But a trio of limitations facing current fMRI technology stands in a way of that goal: time, space, and specificity. At the McGovern Institute for Brain Research at MIT, Alan Jasanoff is developing new chemical sensors, detectable by MRI machines, that will overcome these limitations. The first of these tools, a nano-sized calcium contrast agent, is reported in the October 3, 2006 issue of the Proceedings of the National Academy of Sciences.
