Answer:
Cerrebelum is to: Implicit memory
hippocampus is to explicit memory.
Explanation:
All right, to understand their relationship we need to contextualize.
First of all implicit memory is related to the unconscious tasks we carry on but that we require to remember to be executed. This can be, songs, writing, performing certain exercises. But interesting here everything is related to our motor cognition, this is why the cerebellum is so important here. Because it is related to the motor tasks of our nervous system.
Now, the explicit memory is the cognitive map of learnings and knowledge we maintain as the results of experiences and it is related to the neural cortex and the language zones in our brain. Therefore, the hippocampus is a key player here, because it is related to emotions, learning, and cognition.
