A simple technique for mapping the wiring of the brain — called morphometric similarity mapping — has shown a correlation between how well connected an individual’s brain regions are and their IQ. The results appear in the journal Neuron. According to Seidlitz et al, morphometric similarity mapping provides a novel, robust, and biologically plausible approach to understanding how human brain networks underpin individual differences in...
