Tests of fluid intelligence predict success in a wide range of cognitive activities. Much uncertainty has surrounded brain lesions producing deficits in these tests, with standard group comparisons delivering no clear result. Based on findings from functional imaging, we propose that the uncertainty of lesion data may arise from the specificity and complexity of the relevant neural circuit. Fluid intelligence tests give a characteristic pattern of activity in posterolateral frontal, dorsomedial…

Global Increase in Task-related Fronto-parietal Activity after Focal Frontal Lobe Lesion

The data suggest that, following local frontal lobe damage, there is a global compensatory recruitment of an adaptive and integrated fronto-parietal network in the well-known executive control or multiple-demand system.

Graph lesion-deficit mapping of fluid intelligence

Fluid intelligence is arguably the defining feature of human cognition. Yet the nature of its relationship with the brain remains a contentious topic. Influential proposals drawing primarily on

Fluid intelligence is supported by the multiple-demand system not the language system

A set of frontoparietal brain regions—the multiple-demand (MD) system1,2—has been linked to fluid intelligence in brain imaging3,4 and in studies of patients with brain damage5–7. For example, the

Neural contributions to reduced fluid intelligence across the adult lifespan

Fluid intelligence – the ability to solve novel, complex problems – declines steeply during healthy human aging. Using functional magnetic resonance imaging (fMRI), fluid intelligence has been

Inter- and intra-individual differences in fluid reasoning show distinct cortical responses

This work uses task-based fMRI to show that within and between subject dimensions show both partial overlap and widespread differences, and shows that when difficulty is equated across individuals, those with higher ability tend to show more fronto-parietal activity, whereas low fluid intelligence individuals tends to show greater activity in higher visual areas.

Architecture of fluid intelligence and working memory revealed by lesion mapping

The observed latent variable modeling and lesion results support an integrative framework for understanding the architecture of fluid intelligence and working memory and make specific recommendations for the interpretation and application of the WAIS and N-Back task to the study of fluid Intelligence in health and disease.

Spatio-Temporal Brain Dynamic Differences in Fluid Intelligence

Time re-resolved measures suggest that the left parietal cortex specifically impacts on early processes of attentional focus on task critical features within the MD system, which is novel evidence on the neurocognitive correlates of fluid intelligence suggesting that individual differences are critically linked to an early process of attentioning on task-relevant information.

Activity in the fronto-parietal multiple-demand network is robustly associated with individual differences in working memory and fluid intelligence

This large-sample fMRI investigation found that stronger activity in MD regions was robustly associated with more accurate and faster responses on a spatial working memory task performed in the scanner, as well as fluid intelligence measured independently.

Is the Prefrontal Cortex Important For Fluid Intelligence? A Neuropsychological Study Using Matrix Reasoning

The results failed to support the hypothesis that prefrontal damage would disproportionately impair fluid intelligence, and every prefrontal subgroup the authors studied had Matrix Reasoning scores that were indistinguishable from those of the brain-damaged comparison groups.

Distributed neural system for general intelligence revealed by lesion mapping

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.

The Parieto-Frontal Integration Theory (P-FIT) of intelligence: Converging neuroimaging evidence

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.
