Cognitive fitness of cost-efficient brain functional networks
Superior task performance was positively correlated with global cost efficiency of the β-band network (15-30 Hz) and specifically with cost efficiency of nodes in left lateral parietal and frontal areas. These results are consistent with biophysical models highlighting the importance of β-band oscillations for long-distance functional connections in brain networks and with pathophysiological models of schizophrenia as a dysconnection syndrome. More generally, they echo the saying that “less is more”: The information processing performance of a network can be enhanced by a sparse or low-cost configuration with disproportionately high efficiency.Do we really need vision?
