I'm reading Neuroscience: Exploring the Brain at the moment, and it seems a good textbook for people like me who don't have a hardcore background in biology.
A popular non-textbook on the topic of memory in particular is Kandel's In Search of Memory: The Emergence of a New Science of Mind, which I really liked. The following, by the same author, looks very interesting, and has just gone on my future purchase list: Memory: From Mind to Molecules.
I'm curious to hear opinions from more knowledgeable people than me though.
Good idea. http://www.mathjax.org/ should do the job, I suspect the bulk of the work would be integrating it with the LW post and comment editing widgets.
Good intro lecture to both high-level concepts (long vs short, declarative etc) and anatomical aspects of memory.
