The refinement of localization of intelligence in the human brain is converging onto a distributed network that broadly conforms to the Parieto-Frontal Integration Theory (P-FIT). While this theory has received support in the neuroimaging literature, no functional magnetic resonance imaging study to date has conducted a whole-brain network-wise examination of the changes during engagement in tasks that are reliable measures of general intelligence (e.g., Raven's Progressive Matrices Test; RPM… Expand
Activity in the fronto-parietal multiple-demand network is robustly associated with individual differences in working memory and fluid intelligence
TLDR
It is demonstrated that a core component of individual differences variance in executive abilities and fluid intelligence is selectively and robustly positively associated with the level of activity in the MD network, a result that aligns well with lesion studies. Expand
Interindividual differences in matrix reasoning are linked to functional connectivity between brain regions nominated by Parieto-Frontal Integration Theory
Abstract The Parieto-Frontal Integration Theory (P-FIT) predicts that human intelligence is closely linked to structural and functional properties of several brain regions mainly located in theExpand

Network connectivity correlates of variability in fluid intelligence performance
Abstract Abstract reasoning requires a pattern of spatial and temporal coordination among regions across the entire brain. Recent evidence suggests a very high similarity between spontaneous andExpand

Structural and Functional Brain Parameters Related to Cognitive Performance Across Development: Replication and Extension of the Parieto-Frontal Integration Theory in a Single Sample.
TLDR
Across age and sex groups, better performance was associated with higher volumes, greater GMD, lower MD, lower CBF, higher ALFF and ReHo, and greater activation for the working memory task in PFIT regions, hence PFIT needs expansion into an extended PFIT (ExtPFIT) network incorporating nodes that support motivation and affect.

Where smart brains are different: A quantitative meta-analysis of functional and structural brain imaging studies on intelligence

Cognitive Efficiency in Alzheimer's Disease is Associated with Increased Occipital Connectivity.
TLDR
The concept of "cognitive efficiency" was investigated in Alzheimer's disease patients by operationalizing it as a function of the level of performance shown on the Letter Fluency test, on which, very often, patients in the early stages of AD show unimpaired performance. Expand

The Parieto-Frontal Integration Theory (P-FIT) of intelligence: converging neuroimaging evidence.
TLDR
It is proposed that the P-FIT provides a parsimonious account for many of the empirical observations, to date, which relate individual differences in intelligence test scores to variations in brain structure and function. Expand
Brain spontaneous functional connectivity and intelligence
TLDR
The findings suggest that brain activity may be relevant to the differences in intelligence even in the resting state and in the absence of an explicit cognitive demand, which could provide a new perspective for understanding the neural basis of intelligence. Expand

An integrative architecture for general intelligence and executive function revealed by lesion mapping.
TLDR
The observed findings support an integrative framework for understanding the architecture of general intelligence and executive function, supporting their reliance upon a shared fronto-parietal network for the integration and control of cognitive representations and making specific recommendations for the application of the Wechsler Adult Intelligence Scale and Delis-Kaplan Executive Function System to the study of high-level cognition in health and disease.

Functional brain network efficiency predicts intelligence
TLDR
This is the first study that substantiates the neural efficiency hypothesis as well as the Parieto‐Frontal Integration Theory (P‐FIT) of intelligence in the context of functional brain network characteristics and their relation to psychometric intelligence. Expand
Efficiency of Functional Brain Networks and Intellectual Performance
TLDR
Examining the overall organization of the brain network using graph analysis shows a strong negative association between the normalized characteristic path length λ of the resting-state brain network and intelligence quotient (IQ), suggesting that human intellectual performance is likely to be related to how efficiently the authors' brain integrates information between multiple brain regions.

Distributed neural system for general intelligence revealed by lesion mapping
TLDR
It is suggested that general intelligence draws on connections between regions that integrate verbal, visuospatial, working memory, and executive processes to reflect the combined performance of brain systems involved in cognitive tasks or draws on specialized systems mediating their interactions.

Neural mechanisms of general fluid intelligence
TLDR
Multiple regression analyses indicated that lateral prefrontal and parietal regions may mediate the relation between ability (gF) and performance (accuracy despite interference), providing constraints on the neural mechanisms that support gF. Expand

Brain activation, as measured by functional magnetic resonance imaging, during problem solving in seven young, healthy participants is examined to suggest that fluid reasoning is mediated by a composite of working memory systems. Expand

Recent TCN studies are reviewed with emphasis on those that use ICA, showing that TCNs are robust, and can be consistently identified at rest and during performance of a cognitive task in healthy individuals and in patients with schizophrenia. Expand
