Continuous evaluation of cost-to-go for flexible reaching control and online decisions

Simulation results: narrow and wide targets.
A Mean reaching traces in presence of a rightward mechanical perturbation (represented by the black arrow) for trials initially directed towards a narrow (red) or wide (blue) target. The full and dashed lines represent the trials with and without switch in target structure, respectively. B Mean and standard deviation of the x-position for the different target conditions. Time is aligned with movement initiation and the vertical dotted, full, and dashed lines respectively represent the target switch onset, the force onset, and the time at which the controller was updated. C Simulated end-point variances along the x-axis in absence of mechanical disturbances for trials without (left bar plot) and with change in target structure (right bar plot). The left panel represents the switch from square to rectangle and the right one the switch from rectangle to square. D Mean traces of the transverse velocity in the different target conditions. E Mean traces of the x-motor command for the different target conditions. For comparison with experimental data, the panels A, B and C correspond to the Fig 3 in [17] and the panels D and E correspond to the Fig 4.
