For an initial period (minutes to hours), an explicit or declarative memory, such as a name or event, is registered and stored in the hippocampus, where it can be retrieved by relevant cues. Here, the memory may fall silent and sequentially erased without frequent recalls. Frequent recall attempts turn the memory to long-term (days to months) by a process in the hippocampus called long-term potentiation. Long-term memory is stored in the cortical areas linked to the sensory modalities used in that memory, for example, visual memory will find a space in the visual cortex. In the cortical areas, the memories can remain stored for longer (months to years, called remote memory) or dormant depending on intermittent recalling attempts. The implicit memories, such as driving skills, are registered and stored for the long term (if thoroughly practiced) in the striatum or other basal ganglia components and linked cortical regions. The key to turning memory for the long term is that you value it and keep recalling it.
