Grant awarded to UCSD

 Mingxiong Huang, Ph.D. and Roland Lee, M.D. at UC San Diego have been awarded $2 million from The National Institutes of Health for the purchase of a new, non-invasive magnetoencephalography (MEG) system to study the magnetic fields of the human brain. The MEG machine that can help researchers visualize the brain’s activity by measuring the magnetic fields generated by electrical currents from brain cells (neurons) as they fire in real-time. The MEG can aid scientists and physicians in pinpointing seizure sites, mapping brain function ahead of surgery and developing imaging markers for aiding in the diagnosis of brain disorders.

• A very interesting report on the results of experiments with "fingerprinting" people based on their brain connectome during rest and task-related activity using MEG recordings. The authors conclude that it is possible to identify individuals with some confidence using MEG, and that performance is significantly enhanced during tasks. This is a long and detailed paper, and it seems like a promising area for research. I would have liked to see the authors compare the results using MEG to previous results reported using other modalities.
