US Neuroscience Professor Aron Barbey Lead and Conducted Research To Study Brain Regions That Related To Intelligence, What is Interesting About this Research is That The Data Used Was From Brain Injury Related People Impairments. He stated that "By studying how damage to particular brain regions produces specific forms of cognitive impairment, we can map the architecture of the mind, identifying brain structures that are critically important for specific intellectual abilities".
This study is unique in such a way which enlisted volunteer participants with localized brain damage with penetrating head injuries.
The outcome of the study was stated by Barbey "We found that general intelligence depends on a remarkably circumscribed neural system. With several brain regions, and the connections between them, were most important for general intelligence". Read More Here.
