What is long-term potentiation (LTP) in the context of the microlevel structure of memory?
Explanation
Long-term potentiation (LTP) is a key neural mechanism believed to underlie learning and memory. It is a long-lasting enhancement in signal transmission between two neurons that results from stimulating them synchronously. Essentially, 'neurons that fire together, wire together,' making it a plausible cellular basis for memory formation.
