Neuroscience and intelligence

Neuroscience and intelligence refers to the various neurological factors that are partly responsible for the variation of intelligence within a species or between different species. A large amount of research in this area has been focused on the neural basis of human intelligence. Historic approaches to study the neuroscience of intelligence consisted of correlating external head parameters, for example head circumference, to intelligence. Post-mortem measures of brain weight and brain volume have also been used. More recent methodologies focus on examining correlates of intelligence within the living brain using techniques such as Magnetic Resonance Imaging (MRI), functional MRI (fMRI), Electroencephalography (EEG), Positron emission tomography and other non-invasive measures of brain structure and activity.Researchers have been able to identify correlates of intelligence within the Brain and its functioning. These include overall brain volume, grey matter volume, white matter volume, white matter integrity, cortical thickness and Neural Efficiency. Although the evidence base for our understanding of the neural basis of human intelligence has increased greatly over the past 30 years, even more research is needed to fully understand it.The neural basis of intelligence has also been examined in animals such as primates, cetaceans and rodents.
