Memory is the brain's ability to store information and to use this information when needed. 

All visual and aural sensations produce immediate memories that last only for a couple of seconds. 

If you look at the same object many times, you will remember it better. This is why it is useful to revise things you have already learned when studying. For example, you will remember the nations of Europe or the parts of the brain if you study them multiple times. 

Learning produces new connection between brain cells. For example, when learning a new word, your brain cells form new connections that help you remember its meaning for the rest of your life. 

What things have you learned well? What kinds of things do you remember the best? Answer by commenting.
