      abstract     = {How do patterns of neural activity in the motor cortex
                      contribute to the planning of a movement? A recent theory
                      developed for single movements proposes that the motor
                      cortex acts as a dynamical system whose initial state is
                      optimized during the preparatory phase of the movement. This
                      theory makes important yet untested predictions about
                      preparatory dynamics in more complex behavioral settings.
                      Here, we analyze preparatory activity in non-human primates
                      planning not one but two movements simultaneously. As
                      predicted by the theory, we find that parallel planning is
                      achieved by adjusting preparatory activity within an optimal
                      subspace to an intermediate state reflecting a trade-off
                      between the two movements. The theory quantitatively
                      accounts for the relationship between this intermediate
                      state and fluctuations in the animals’ behavior down at
                      the trial level. These results uncover a simple mechanism
                      for planning multiple movements in parallel and further
                      point to motor planning as a controlled dynamical process.},
