Does Smarter Mean More Stable? IQ Test Score Associates With Brain Network Stability

“The interconnections and communication between different regions of the human brain influence our behaviour in many ways. This is also true for individual differences in higher cognitive abilities. The brains of more intelligent individuals, as measured by a standardised IQ test, are characterised by temporally more stable interactions in neural networks. This is the result of a recent study conducted by Dr Kirsten Hilger and Professor Christian Fiebach from the Department of Psychology and Brain Imaging Center of Goethe University Frankfurt in collaboration with Dr Makoto Fukushima and Professor Olaf Sporns from Indiana University Bloomington, USA. The study was published online in the scientific journal ‘Human Brain Mapping’ on 6th October”.
