(a) Global brain network whose activity can be represented in the cognitive space by robust stable heteroclinic channels (SHCs). (b) SHC that includes a chain of metastable states, informational patterns. The gradient colours in the vicinity of each metastable state represent the combination of brain elements that generate the corresponding pattern. Dashed lines with arrows represent the stable and unstable separatrices of the mestastable states, which determine the structure of the information flow. (Online version in colour.)
