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: Just after the perturbed mappings were introduced, BCI performance was impaired ( Fig.
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: In both cases, performance was impaired once the new mapping was introduced, and we observed whether the monkeys could learn to regain proficient control of the cursor. Just after the perturbed mappings were introduced, BCI performance was impaired ( Fig. Performance improved for the within-manifold perturbation ( Fig.
