Although it is commonly accepted that learning and memory occur via enduring changes in neuronal properties such as synaptic strength within a network of neurons, many details of these processes remain unknown, including the mechanisms responsible for the persistence and maintenance of memory over long periods of time.

On a macro scale, neuroscientists now know (more or less) where memories are 'stored' in the human brain. The brain's hippocampus, the amygdala, the striatum and the(for example) are known to be involved in some way, because individuals who suffer damage (either by injury or disease) to those areas are prone to memory loss of various kinds.
Different modes of memory (short-term, long-term, motor memory etc) have been extensively classified and described, but researchers aren't yet in complete agreement about the models.
On the small, neuronal scale - at 'component level' so-to-speak â the mechanisms by which complex memories are stored and retrieved are still a complete mystery.
