How do neurons create memories?
How do connections between neurons become strengthened, so that the connection is 'remembered'? Scientists know that if they give an electrical impulse to a pair of neurons, the two will communicate more easily in the future. This process is known as long-term potentiation (LTP). The effect can last for weeks, or even months – long enough to make a memory. LTP is especially obvious in the hippocampus, one of the areas of the brain active in memory.
