Imaging study shows brain activity may be as unique as fingerprints
A person’s brain activity appears to be as unique as his or her fingerprints, a new Yale-led imaging study shows. These brain “connectivity profiles” alone allow researchers to identify individuals from the fMRI images of brain activity of more than 100 people, according to the study published Oct. 12 in the journal Nature Neuroscience. Finn and co-first author Xilin Shen, under the direction of R. Todd Constable, professor of diagnostic radiology and neurosurgery at Yale, compiled fMRI data from 126 subjects who underwent six scan sessions over two days. Subjects performed different cognitive tasks during four of the sessions. In the other two, they simply rested. Researchers looked at activity in 268 brain regions: specifically, coordinated activity between pairs of regions. Highly coordinated activity implies two regions are functionally connected. Using the strength of these connections across the whole brain, the researchers were able to identify individuals from fMRI data alone, whether the subject was at rest or engaged in a task. They were also able to predict how subjects would perform on tasks. Read full article from Yale News here.

Yale Professors awarded White House BRAIN initiative grant
Two Yale School of Medicine professors have received a federal grant supported by President Obama’s BRAIN Initiative. R. Todd Constable, professor of diagnostic radiology, and Michael C. Crair, professor of neurobiology, will use the nearly $5 million National Institutes of Health award over three years to develop experimental and analytic methods for examining neuronal activity across scales, from the single cell to the whole brain.

Dr. Gigi Gailiana appointed as Assistant Professor in the department of Diagnostic Radiology
We are very pleased to announce that Dr. Gigi Galiana was appointed Assistant Professor in the Department of Diagnostic Radiology on September 1, 2011. Dr. Galiana’s research spans MR methodology development with an emphasis of novel methods for generating tissue contrast particularly in cancer detection applications. She also is very active in the development of novel nonlinear gradient spatial encoding strategies for accelerated parallel imaging. Dr. Galiana performed her graduate work at Princeton University and received her Ph.D. in 2008.
She joined the Yale MRRC in 2008 as a Postdoctoral Fellow and was promoted to Associate Research Scientist in 2011. Dr. Galiana is the author of 14 papers and multiple patents. Her ground-breaking work on exploiting multiple quantum coherences to broaden the capabilities of MRI earned her a first author Science paper. She received a L’Oreal Women in Science grant in addition to a Ford Foundation grant and has been a key contributor to numerous projects in the MRRC.

Daniel Coman is involved in two new patents in the field of magnetic resonance research.
The first invention is directed towards contrast agents for magnetic resonance imaging (MRI) and/or spectroscopy (MRS) and methods of using these contrast agents for altering the MRI and/or MRS signals in samples, in vitro or in vivo, and more specifically to paramagnetic metal ion macrocyclic complexes as contrast agents and methods based on detection of exchangeable and non-exchangeable protons with techniques that have been dubbed as chemical exchange saturation transfer (CEST) and biosensor imaging of redundant deviation in shifts (BIRDS), respectively.
The second invention describes a fast, reliable, and simple method for estimating the power (i.e., heat) deposition by the radio-frequency (RF) pulses applied during any magnetic resonance imaging (MRI) and/or
spectroscopy (MRS) experiments. Prior to implementation in vivo, all MRI or MRS pulse sequences must undergo a series of in vitro tests to assess the RF power deposition, the proposed method will provide the
quantitative data for such tests. The in vitro sample contains a known amount of a magnetic resonance temperature molecular probe to estimate temperature changes in the sample.
