It is generally accepted that precise motor control in our daily life depends on acquisition of an internal model. One motor learning for an internal model is necessary for execution of precise movements in our daily life. There are two hypothetical internal models for motor learning: where to move (i.e. calculation of destination for a given motor command) or how to move (i.e. calculation of motor command for a target). There has been long-standing controversy over “which internal model is actually working in our brain?,” for more than 30 years.

Takeru Honda, PhD, a lead author of this study, and his coauthors thought that both internal models are necessary to execute precise movement. If we learn where to move,
