Jack doesn't need to look at his keyboard while typing. his fingers automatically move over the keys as he types information into the computer. in the context of memory storage, which part of jack's brain is active when he is performing this?

For Jack to be able to type without looking at his keyboard, he is using a part of memory which is known as Implicit memory. Implicit memory involves the ability to recall experiences, movements, and actions without giving serious thought. This is made possible through going over an experience repeatedly. The part of the brain responsible for Implicit memory is the cerebellum.

The cerebellum is the active part of the brain which allows these functions to exist. The cerebellum uses receptors that travel through the spinal cord in order to allow the body to appropriately react to external forces through movement and mobility. The cerebellum aids the human body in learning various movements, such as balance, and being able to type without looking. While the cerebellum is not directly responsible for human movement, it is responsible for allowing better accuracy and coordination in regards to movement.

This includes actions such as riding a bicycle or reading a text. At first, we may pick up every tiny detail within our actions but over time, those little details become subconscious and we are able to recall these actions to perform without thinking. For Jack, this is the same occurrence as being able to type without looking at a keyboard involves the use of the cerebellum to improve overall memory from human movement.
