            Nerves are the connections between your brain
                   and your body. Sensory nerves send the
                     brain messages from sensors in your
                     body such as ears, which detect sounds,
                       and nerve ends in your skin, which
                       react to touch. Motor nerves go out
                    from your brain telling muscles to move.

            Memories for keeps

            Some memories fade quickly, but psychologists have found
            your brain keeps memories longer in various ways.















            Your brain learns some things   Other things you learn     Still other memories are
            only by repeated practice,     more quickly, such as       formed by individual
