There's tons of evidence linking LTP to learning and memory functions, which makes sense. How it all works, however, is a mess (like all of neuroscience, that's what makes it fun and interesting!). In today's issue of Science, a team of researchers have found that recycling endosomes seem to act as the 'storehouse' for receptors bound to and from the membrane. When they stimulated LTP, they found that these organelles do the legwork of upping (or, in the converse, reducing) the cell's receptor densities. But, surprisingly, they also saw increased recycling of other molecules as well! This is one of the fun things about science: the more you learn, the more mysteries you find!
