It can be fun to hear a catchy tune()in your head-until that tune begins
to
play over and over again!Songs that get stuck in our brain are called earworms.An
earworm can stay in your head after you listen to the tune play out loud.But it can alsc
occur if something makes you remember the song-like visiting the place where you
irst heard it
Scientists have studied earworms for years.They have found that some tunes are
more likely to stay in your head than others.For example,earworms are often faster
have an easy-to-remember melody(旋律)，and have special changes in pitch(音高)，
By examining brain scans,scientists have learned what happens in your head
when you have an earworm.When you hear music-or even imagine hearing it-part
of the brain called the auditory cortex(听觉皮层)becomes active.This part processes
sounds and sends messages to other parts of the brain connected to memory and
feelings.Some scientists think your brain can keep sending these signals for a short
time,which causes the song to repeat in your mind.
What would cause the human brain to repeat the same song in the first place
Scientists are still not sure.But long ago,before writing was invented,we passed
information through songs.So,we may have developed a habit of keeping music in our
heads to help remember important information.
Whatever the reason,when a tune gets stuck,it can be really annoying!Luckily
there may be ways to get rid of an earworm.You can listen to another song or do a
puzzle to stop yourself from concentrating on it.Or try chewing gum,which affects
how your brain remembers music.Even if you do nothing,a stuck song will eventually
go away on its own.Now,that must be music to your ears!
