====Parieto-frontal integration theory====
{{main|Parieto-frontal integration theory}}
In 2007, [[Behavioral and Brain Sciences]] published a target article that put forth a biological model of intelligence based on 37 peer-reviewed neuroimaging studies ([[Rex Jung|Jung]] & [[Richard J. Haier|Haier]], 2007).  Their review of a wealth of data from functional imaging ([[functional magnetic resonance imaging]] and [[positron emission tomography]]) and structural imaging ([[diffusion MRI]], [[voxel-based morphometry]], [[in vivo magnetic resonance spectroscopy]]) argues that human intelligence arises from a distributed and integrated neural network comprising brain regions in the frontal and parietal lobes.<ref>{{Cite journal

A recent lesion mapping study conducted by [[Aron K. Barbey|Barbey and colleagues]] provides evidence to support the P-FIT theory of intelligence.<ref>{{cite journal|last1=Barbey|first1=Aron K.|last2=Colom|first2=Roberto|last3=Solomon|first3=Jeffrey|last4=Krueger|first4=Frank|last5=Forbes|first5=Chad|last6=Grafman|first6=Jordan|title=An integrative architecture for general intelligence and executive function revealed by lesion mapping|journal=Brain|volume=135|issue=4|pages=1154–1164|doi=10.1093/brain/aws021|pmid=22396393|pmc=3326251|year=2012}}</ref><ref>{{cite news|author1=HealthDay|title=Researchers Map Brain Regions Linked to Intelligence|url=http://health.usnews.com/health-news/news/articles/2012/04/13/researchers-map-brain-regions-linked-to-intelligence|agency=U.S. News & World Report|date=2012-04-13}}</ref><ref>{{cite web|last1=Yates|first1=Diana|title=Researchers Use Brain-Injury Data to Map Intelligence in the Brain|url=http://news.illinois.edu/news/12/0410braininjury_AronBarbey.html|website=University of Illinois News Bureau|publisher=University of Illinois}}</ref>

Brain injuries at an early age isolated to one side of the brain typically results in relatively spared intellectual function and with IQ in the normal range.<ref>{{cite journal |last1=Bava |first1=Sunita |last2=Ballantyne |first2=Angela O |last3=Trauner |first3=Doris A |title=Disparity of Verbal and Performance IQ Following Early Bilateral Brain Damage |journal=Cognitive and Behavioral Neurology |volume=18 |issue=3 |pages=163–70 |year=2005 |pmid=16175020 |doi= 10.1097/01.wnn.0000178228.61938.3e|s2cid=30150030 }}</ref>
