You have been learning how to play the guitar and realize that this would be a great example to use to help you remember the various pathways and cells of the cerebellum that are working in unison to fine tune your ability to play this instrument. You break down your guitar playing into the following steps:

1. The cerebellum is getting a ton of information as you try to play the guitar, including where your fingers are on the neck of the guitar, the rate and rhythm of your strumming, and the actual sounds that are generated.
2. The cerebellum integrates this information and sends it back out to the various parts of your body to carry out this highly coordinated movement.
3. If you end up playing a C chord when you intended to play a D chord, this information is also sent to the cerebellum to correct your movements the next time you play the same song.

Identify which pathways into, within, and out of the cerebellum, as well as the specific cells within the cerebellum, that carry out each of these steps.
