The parieto-frontal integration theory (P-FIT) considers intelligence to relate to how well different brain regions integrate to form intelligent behaviors. The theory proposes that that a network of brain regions, including regions within frontal, parietal, temporal, and cingulate cortices, underlie the biological basis of human intelligence. These regions, which overlap significantly with the Task-Positive Network, allow the brain to communicate and exchange information efficiently with one another. Support for this theory is primarily based on neuroimaging evidence, with support from lesion studies. The P-FIT is influential in that it explains the majority of current neuroimaging findings, as well as increasing empirical support for cognition being the result of large-scale brain networks, rather than numerous domain-specific processes or modules.〔Bressler, S. L., & Menon, V. (2010). Large-scale brain networks in cognition: emerging methods and principles. ''Trends in Cognitive Sciences, 14''(6), 277–290. doi:10.1016/j.tics.2010.04.004〕 Indeed, a review of the neuroscience of intelligence argues that the P-FIT is “the best available answer to the question of where in the brain intelligence resides”.〔Deary, I. J., Penke, L., & Johnson, W. (2010). The neuroscience of human intelligence differences. ''Nature Reviews Neuroscience, 11''(3), 201-211. ()〕 ==The theory== General intelligence requires specific brain regions and incorporates: * Sensory processing, primarily in the visual and auditory modalities, including specific temporal and parietal areas * Sensory abstracting and elaboration by the parietal cortex (especially the supramarginal, superior parietal, and angular gyri) * Interaction between the parietal cortex and frontal lobes for hypothesis testing available solutions * Response selection and inhibition of competing responses by the anterior cingulate This theory proposes that greater general intelligence in individuals results from the greater communication efficiency between the dorsolateral prefrontal cortex, parietal lobe, anterior cingulate cortex, and specific temporal and parietal cortex regions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parieto-frontal integration theory」の詳細全文を読む スポンサード リンク
