Brain scans reveal what you are remembering

from io9:

10 subjects were shown three film clips multiple times, then asked to remember them while inside the fMRI scanner. It turned out to be relatively easy to trace the neurological pathway between viewing something and putting the memory into short-term storage in the hippocampus.

Above you can see a “heat map” of which parts of the hippocampus are active as memories get stored. Using specialized software, the researchers could detect and decode each memory.
