Why do we forget?

196 views

I was thinking how sometimes when you’re looking for something and eventually find it, you then remember leaving there.

So my question is, why do we forget certain stuff. Specially since certain triggers will bring those memories back meaning they never actually left our memory.

oversimplified: your brain cleans out memories it doesn’t need all the time. we only have so much “storage” for memories, so our brain gets rid of things it doesn’t need. what you ate for breakfast 5 years ago, every time you pissed 3 days ago, etc.

memories are just sequences of neurons being activated in a certain way. after a time of said neurons not being fired, or “remembered”, the link degrades.

the more you remember a certain memory, the more the neural bond strengthens. over time it may degrade and some parts get forgotten or changed.

tldr; neural bonds degrade over time, and the brain cleans out unused files it doesn’t need.
