Dr Klados presented the effect of crystalized IQ in cerebellum’s functional network. Small world properties were examined and the concept of the Minimum Spanning Tree was employed in order to overcome graph comparison issues. The presented analysis linked the lower SWN-ness in high IQ females, in relation to low-IQ females and in relation to men, to a more efficient network organization in women, thereby reflecting different hemispheric organization between the two sexes.
