Ahighly trained classical guitarist sustained brain damage as the result of an automobile accident. despite recovering most of her memory, language, and cognition, she is unable to play the guitar. because her loss of function appears principally to affect her motor control and coordination, it is most likely that her was damaged in the collision.

cerebellum

Explanation:

This part is in at the bottom of the brain. The cerebellum is the side that is sensible of being damage because of it position. At the same time, when there is a damage here is clear because the movements are not controlled and they are without accuracy, so the fine locomotricity is lost, like play the guitar.

Also the posture is lost because the cerebellum also is the responsible to connect the sensitivity cells and the motor cells.
