News Finding: The results showed that the subjects learned to generate some neural activity patterns more easily than others, since they only sometimes achieved accurate cursor movements.
Paper Finding: These data are consistent with the hypothesis that relatively little learning occurred during the outside-manifold perturbations in comparison to the within-manifold perturbations.
News Context: "It helps scientists study the dynamics of brain circuits that may explain the neural basis of learning." The results showed that the subjects learned to generate some neural activity patterns more easily than others, since they only sometimes achieved accurate cursor movements. The harder-to-learn patterns were different from any of the pre-existing patterns, whereas the easier-to-learn patterns were combinations of pre-existing brain patterns.
Paper Context: 0.05). These data are consistent with the hypothesis that relatively little learning occurred during the outside-manifold perturbations in comparison to the within-manifold perturbations. Number of within-manifold perturbations, n 5 27 (monkey J), 14 (monkey L); outsidemanifold perturbations, n 5 33 (monkey J), 15 (monkey L).
