Kawai Et Al

Kawai et al.'s 2015 study used rats to explore how lesions of the motor cortex impact the ability to learn and perform motor sequences. What results regarding the motor cortex did this study yield?

A) Cerebellar activity, but not motor cortex activity, was necessary to learn a new motor sequence.
B) Motor cortex activity was more critical than cerebellar activity in enabling rats to overcome their dislike for reward delay.
C) Once a new motor sequence had been learned, the cerebellum was sufficient to produce that motor sequence, even without motor cortex input.
D) Neither the cerebellum nor motor cortex was necessary to learn a new motor skill.
