Brain Morphology in Extraordinary Geometrician Harold Coxeter: implications for connectivity

The findings suggest that HC's exceptional abilities may be associated with increased connectivity mediated by WM tracts in specific brain regions, particularly those related to visuospatial processing and mathematical cognition. These results support the general hypothesis that WM connectivity may play a key role in intelligence variability, especially in domains involving spatial and mathematical processing. We found no evidence for GM differences. Some other studies of cognitive expertise showed increased GM density, but used transformed measures of relative GM density, whereas our method allows direct quantification of tissue volumes. This study highlights the potential link between structural brain differences and variations in cognitive ability, offering insight into the neurobiological basis of some aspects of human intelligence.
