The study analyzed data collected using magnetoencephalography (MEG), a highly advanced imaging technique that detects and maps subtle changes in the magnetic fields produced by activity within the brain. Its principal author was Timothy P.L. Roberts, Ph.D., Vice Chair of Research in the Department of Radiology of the Children's Hospital of Philadelphia, holder of the Oberkircher Family Chair in Pediatric Radiology and Professor of Radiology at the University of Pennsylvania.
Tal Kennet, Ph.D., scientific director of Dr. Martha Herbert’s TRANSCEND research laboratory at Mass. General Hospital, presented similar findings, also derived from MEG scans, in a talk at NESCA on December 11, 2009.
