How are memories stored at a cellular level?

Moreover, are short term memories stored by a different physiological mechanism than long term memories? Or is all memory and learning achieved by the same fundamental cellular changes to neurons?

Lots of people think that it's CamKII/NMDAR. It sits in between neurons that are connected. As they fire together, the complex strengthens the association between the two neurons. The process involves successive incidents of calcium binding. This is called a "molecular coincidence detector." As the neurons fire together more frequently, they become wired together. Neat!
