Better technology enables ever more precise analysis of workings of memory.

One of the main targets in memory research is to pinpoint how the brain encodes individual memories. Architecturally, at least, researchers have made great progress on this question in very recent years. Whilst the hippocampus is important for encoding, the memory itself is highly distributed across the brain. One researcher speculates that up to 30 different brain regions are involved. Thus, a memory is effectively encoded in its own uniquely dedicated neuronal network. This network is then called upon when the memory is retrieved.
