摘要：

To understand how cognition and response selection processes might emerge from dynamic brain systems, we analyzed reaction times during the performance of both a working memory task and a choice reaction time task at different levels of cognitive load. Our findings suggest a continuous transitiontuned by loadfrom random behavior toward scale-free like behavior as an expanding connectivity process in a network poised near a critical point.
