Abstract
The study of the relationship between brain connectivity and cognitive abilities is of great importance for a better understanding of the human mind. We propose to tackle this issue with the help of several connectivity measures, assessing the strength of their association with the subjects’ performance in some standard neuropsychological tests. The novelty of this work is the use of these connectivity metrics outside the field were they originated, which is their association with the subjects’ chronological age. The results obtained from an experiment with data from the Human Connectome Project show positive correlations between the proposed connectivity measures and the aforementioned neuropsychological indices. The outcome of this approach yields correlation values which compare favourably with state-of-the-art research and show that those measures could be relevant across several fields of study.
