Network neuroscience theory best predictor of intelligence

/in /by

 

Recent evidence in network neuroscience indicates that general intelligence may depend on system-wide network mechanisms, suggesting that the spatially localized predictions of standard theories may be necessary but not sufficient to account for the neural architecture of intelligence. To investigate this key theoretical issue, we directly compared the predictions of local versus global theories within a connectome-based predictive modeling framework, demonstrating that general intelligence can be predicted by local functional connectivity profiles but is most accurately explained by global profiles of whole-brain connectivity.

“Our goal in this project is to improve how the individual war fighter identifies, measures, and tracks personalized biomarkers and therefore to help them prepare more effectively for specialized roles in their military career” said Aron Barbey, a professor of psychology. “We will work closely with Lawrence Livermore National Laboratory as part of the test and evaluation team for the Measuring Biological Aptitude program.”

The Defense Advanced Research Projects Agency will fund two projects for research on human performance optimization within United States war fighters at the Beckman Institute for Advanced Science and Technology.

Larger sample sizes needed to increase reproducibility in neuroscience studies

/in /by

CHAMPAIGN, Ill. — Small sample sizes in studies using functional MRI to investigate brain connectivity and function are common in neuroscience, despite years of warnings that such studies likely lack sufficient statistical power. A new analysis reveals that task-based fMRI experiments involving typical sample sizes of about 30 participants are only modestly replicable. This means that independent efforts to repeat the experiments are as likely to challenge as to confirm the original results.
