  • Hey there. Welcome to Life Noggin.

  • The brain is a pretty cool organ, but sometimes it can fail us.

  • Like when we forget someone's name, or blank on a test.

  • But how can someone just forget something like that?

  • Well, to start off I want you to imagine what a penny looks like.

  • You're probably imagining Abraham Lincoln looking off to the right.

  • And that the coin is copper.

  • But you probably didn't recall the phrase above the Lincoln Memorial on the back of the penny.

  • If you did, congrats!

  • But the reason we may have not remembered every single aspect of the coin is because frankly, it doesn't matter!

  • All we need to know is how to distinguish a penny from any other coin, so we only remember the important parts, and store them in our long-term memory.

  • All of the small details of any experience like you watching this video for example are combined into one event in your brain's hippocampus.

  • You are essentially a network of neurons that records the association linked to the memory.

  • And any of those associations, like hearing the name Blocko, can bring back that memory. But problems arise...

  • When there is more than one memory associated with a given cue.

  • If you ever met someone who looks like an old friend, it may be difficult to remember this new person's name because that face already has some other meaning to you.

  • And the memories are interfering with each other.

  • Decay theory states that a memory slowly fades over time if it's not rehearsed often.

  • So if you do not frequently think about something, you'll forget it.

  • It makes sense, but you also have to be paying attention in the first place if you ever want to recall that information.

  • So, what is something that you always forget?

  • Did...did you forget it?

  • I'm terrible with birthdays but luckily Facebook is there to save the day.

  • Speaking of which, if you want to you can follow me on there.

  • As usual, I'll be answering a new question every Thursday, so ask anything you want to know in the comments or on Facebook and Twitter.

  • I'm Blocko. This has been Life Noggin.

  • Don't forget to keep on thinking!

Hey there. Welcome to Life Noggin.
