Preparation and execution of ballistic movements

(A) Under a dynamical systems view of motor control (Shenoy et al., 2013), movement is generated by M1 dynamics. Prior to movement, the M1 population activity state $\mathit{x}\left(t\right)$ must be controlled into an optimal, movement-specific subspace in a phase of preparation; this requires internally generated control inputs $\mathit{u}\left(t\right)$.
