Movement speed is biased by prior experience
How does the motor system choose the speed for any given movement? Many current models assume a process that finds the optimal balance between the costs of moving fast and the rewards of achieving the goal. Here, we show that such models also need to take into account a prior representation of preferred movement speed, which can be changed by prolonged practice. In a time-constrained reaching t...

24 How does the motor system choose the speed for any given movement? Many current 25 models assume a process that finds the optimal balance between the costs of moving fast and the 26 rewards of achieving the goal. Here we show that such models also need to take into account a prior 27 representation of preferred movement speed, which can be changed by prolonged practice. In a 28 time-constrai...
متن کاملDazzle coloration and prey movement.
Many traits in animals reduce the rate of attack from visually hunting predators, including camouflage, warning signals and mimicry. In addition, some animal markings may reduce the likelihood that an attack ends in successful capture. These might include dazzle markings, high-contrast patterns that make the estimation of speed and trajectory difficult. However, until now, no study has experime...
متن کاملNeuronal activity in the ventral part of premotor cortex during target-reach movement is modulated by direction of gaze.
We recorded 200 neurons from the ventral part of the premotor cortex (PMv) and 110 neurons from the primary motor cortex (MI) of a monkey performing a visually cued arm-reaching task with a delay. We compared neuronal activity in the premovement period while the monkey reached the target with the eyes fixating on either a left or right fixation target. Our data demonstrate that about half of th...
متن کاملCoupling between reaching movement direction and hand orientation for grasping.
In a previous work, we demonstrated that orientation of the hand in the horizontal plane (azimuth) at the time of grasping depends on the direction of the reaching movement in the horizontal plane. Here we report three experiments to further investigate the generality of this coupling. Azimuth of the hand for grasping was studied while subjects were reaching for objects placed at various locati...
