The lateral prefrontal cortex is a region of interest because those who have injuries to that part of the brain often have issues with common, every day tasks such as planning their day. The LPFC is thought to be important for "cognitive control capacity," which can be used to predict future outcomes such as success in school and the workplace. It was found by van den Heuvel et al. that higher intelligence individuals employ more efficient whole-brain network organization. This had led to the thought that cognitive control capacity may be supported by these whole-brain network properties. The 2012 study used a theoretic approach to neuroimage data known as global brain connectivity (GBC) or weighted degree centrality. GBC let the researches look closely at specific regions and their range of connectivity. It was then possible to examine each region's role in human cognitive control and intelligence. The study used fMRI to acquire data and examine each region's connectivity.<ref>{{cite journal|pmid=22745498 | doi=10.1523/JNEUROSCI.0536-12.2012 | volume=32 | issue=26 | title=Global connectivity of prefrontal cortex predicts cognitive control and intelligence | pmc=3392686 |date=June year=2012 | month=June | journal=J.
