Mindblog backlog...

Here is my second offering of links to a few bits of work that I find interesting, but that are so far down my list of potential blog postings that they are unlikely to make it into a regular post, and might be of interest to some MindBlog readers.

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.
