Summary

When memories are first formed, they are vulnerable. New memories can be disrupted by strong stimuli or by other learning, or they can simply fade. In this chapter the author explores some possible factors that may make cerebellar motor memories especially durable. It is possible that some cognitive skills, such as language learning and math computation, may follow the same rules as motor skills. The chapter proposes mechanisms for learning both in the cortex and in the DCN. Some scientists think that the DCN has a unique role as a site for long-term storage. A memory that is encoded by BK-channel phosphorylation would remain until it is degraded by phosphatase activity. This could confer unusual stability on memory traces in the vestibular nuclei. Intrinsic plasticity might participate in transferring the memory trace to the DCN during consolidation.
