News Finding: Cognitive Flexibility: why learning new tasks may be associated with the connectivity among neurons. 
Paper Finding: These results support our hypothesis that the structure of a network determines which patterns of neural activity (and corresponding behaviours) a subject can readily learn to generate.

Paper Context: 2) , indicating that it was difficult to learn to generate new co-modulation patterns, even when those patterns would have led to improved performance in the task. These results support our hypothesis that the structure of a network determines which patterns of neural activity (and corresponding behaviours) a subject can readily learn to generate. Two additional lines of evidence show that BCI control was more learnable when using within-manifold perturbations than outside-manifold perturbations.
