It’s not one I listen to often, yet for some factor I knew eextremely word. I turned to the next station, and also I could sing the song playing on that one, too. I then popped in a Ben Folds CD and I remembered song after song. Which made me wonder — exactly how many songs deserve to our brains actually remember? And if I had a way to dump some of them, would certainly I be to remember things that are possibly even more vital, choose wbelow I left my keys?
The brief answer: no.
“Your brain has actually virtually an infinite capacity for memory,” sassist Dr. Emily Machild, who research studies memory and also cognition at the University of Louisville. “It have the right to actually store about 2.5 petabytes of memory.”
A petabyte is a million gigabytes, so it’s pretty huge. To put that in terms of digital memory, Mason sassist, if your brain was a smartphone on which you downloaded TV mirrors, it might document 300 years of constant TV prior to founding to run out of space. But your brain’s short-lived, quick recall memory has more restrictions. “You require more cues to remember things like that, and also for somepoint like your keys, where you could leave them in a different spot eexceptionally day, that’s sort of confusing to your brain to remember,” she said. And, in contrast, tright here are a couple of reasons why we remember music so well. Some of it has to execute through how our brains are hardwired to latch onto repetition and rhyme — aspects most songs have. “In elementary college, that’s why points are put to song,” Machild sassist. There’s also a tiny facet of muscle memory. It’s sort of choose if you play basketsphere, you acquire to the allude where you don’t need to coach yourself through each step of dribbling. After a while, you execute it without reasoning. When you sing alengthy to a song enough times, muscle memory between your brain and also mouth type of kicks in.

But according to Machild there’s somepoint about music that hits us on an emotional level, and that especially aids in memory.“Your brain loves emotions,” Makid said. “That really helps you remember points.”This can happen through songs that you associate through being happy or in love. “A song with a positive valence can activate your reward cortex, and also your brain progressed to sort of overview you toward rewards,” Maboy said. The very same is true for songs that make you feel really sad. Our brain recognizes these exceptionally huguy emovements and helps us remember what triggered those.
And our brains aren’t simply excellent at remember and also reciting lyrics. Thanks to these emotional bonds, often as soon as we hear music — also music from years ago — it deserve to take you ago to a details allude in time.

Makid said that’s why existing research study into Alzheimer’s and also dementia is taking a closer look at exactly how music deserve to provide a gatemethod into old memories.
This, she said, is one method our brains assist to preserve the a lot of necessary components of what makes you, well, “you.”
