News Finding: "We found that the brain works in a similar way during learning.
Paper Finding: Following within-manifold perturbations, performance was impaired briefly (Extended Data Fig.
News Context: Understanding the ways in which the brain's activity can be "flexed" during learning could eventually be used to develop better treatments for stroke and other brain injuries. "We found that the brain works in a similar way during learning. We found that subjects were able to more readily recombine familiar activity patterns in new ways relative to creating entirely novel patterns."
Paper Context: First, perturbation types differed in their after-effects. Following within-manifold perturbations, performance was impaired briefly (Extended Data Fig. Following outside-manifold perturbations, performance was not impaired, which is consistent with little, if any, learning having occurred (Extended Data Fig.
