Topic: force field perturbation

Recent studies of motor control have shown that the neural population activity in motor cortical areas has a low-dimensional structure: a low number of latent dynamical factors that explain a large fraction of neural variability. It is unclear, however, whether this low-dimensional structure corresponds to task instructions or to behavioral output, since both variables are strongly correlated with one another. To address this question, we analysed neural recordings from premotor and motor cortices of monkeys engaged in a center-out reaching task with a force field perturbation. The perturbati
