Recent evidence from our lab indicates that LTP shares an
important property with memory consolidation: it is consolidated by
natural reinforcement. Nevertheless, the hypothesis, that LTP-like
mechanisms or other forms of enhanced synaptic efficacy are basic
elements in learning is not unequivocally supported. Skepticism aside,
LTP is an accessible experimental model that is optimally equipped for
the investigation of the cellular and molecular machinery involved in
synaptic weight changes.
