fMRIs reveal brain's handling of low-priority ideas

orrelated to genetic factors. "We found that more than 40 percent of the between-subject variance in functional connectivity within the default-mode network was under genetic control," Dr. Fox said.

Based on this information, it is possible new diagnostic tools could be considered for various psychiatric or neurological illnesses, he said.

The study also included collaborators from the Yale University School of Medicine, the University of Oxford in Oxford, U.K., and Imperial College in London, U.K. The project is an outgrowth of longstanding collaborations between the UT Health Science Center and the Southwest Foundation for Biomedical Research using tools for gene discovery. It is also a result of substantial collaborations between the Research Imaging Institute and Oxford to develop novel applications of imaging methods.

Future directions

"One long-term research goal is to test whether other intrinsically connected networks are also under genetic control, which we expect they will be," Dr. Fox said. "We also want to identify the genes that are controlling the default-mode network and other networks, and identify disorders associated with their abnormalities. A final goal is to develop treatment strategies."
