eli5: how does our brain choose to “forget” certain things and remember others?

317 viewsBiologyOther

I was thinking about this the other day as I realized I was able to remember the face and name of my 3rd grade teacher but cannot remember any other teachers from elementary or middle school.

Is there a certain priority list our brain uses? Why do minor things in our lives often stay remembered, when other things we may have viewed as more important get forgotten?

I dare say you had a different relationship to that particular teacher because you added some extra material to be stored – probably unconscious – which resulted in her being able to be retrieved easily.

As far as I am aware we have no complete idea how we store things in our brain but we know that we dont store like a computer. Most of what we store are fragments or patterns and we fill gaps where needed. Combining emotions with persons makes a stronger connection of retrieval than just a common acquaintance for example.

So everything meaningful in terms of emotions usually gets a ‘higher’ priority in your brain due to extra connections to the ‘data’.
