The best current literature, and I think in such a fast moving field the
current literature is the best as opinions change very fast in this
highly contenscious field, is as follows.
Okay, a good general introduction to learning/memory and LTP is Bliss &
Collingridge (1993) in Nature.
More recently, on the role of LTP in learning dependant plasticity and
developmental plasticity check out the last five weeks nature. Approx 4
weeks ago in Nature were two papers on the role of LTP during the
critical period for developmental plasticity of mouse visual cortex and
rat mechanosensory bristles. About three weeks ago was a post-synaptic
model for the origin of hippocampal LTP (hypothesised as underlying
learning/memory). These three papers themselves should give you plenty
to work with in the way of references. Otherwise look up LTP on Medline
or a similar reference database.
More specifically, for the role of LTP in learning/memory look up papers
by Kandel, Nicoll (mostly physiology), Malenka, or Tonegawa (knockouts
and their effect on LTP).
What it is most important to remember however is that LTP is only
causally associated with learning/memory. All knockouts that show
deficiency in learning/memory do not necessarily show a defect in LTP
(for example PKC knockout). Is some other form of plasticity involved?
The answer is probably yes, look up Long Term Depression, not many papers
but they are about.
