Is it possible for a brain to be full?

Probably, but old data gets over-written so the new data will still get saved.

Well, even in the course of a few hours, or less, a person’s attention can be saturated.

But I gather by “full” you are thinking of it in terms of a computer memory or something, and 1) that’s not a good analogy for the way brains work and 2) no, brains have almost unimaginable ability to remember things.

However, memory has many limits as well (which also aren’t really analogous to computer memory), and certainly if a person tries to remember many things, depending on the person and what/how they’re trying to remember things, that they can and will encounter various sorts of difficulties.

My brain feels full and like it has holes in it at times. My memory is nothing like it used to be. I’m often very aware when someone is telling me information that I’m not going to retain it. It’s half I don’t care and half my brain just doesn’t have space anymore.

I don’t think the human brain has infinite data storage ability. No problem. Just erase the old memories to make room for new information. I do that frequently with my computer.

I think yes or or no. If you think of the brain in the terms of a computer.

There is the part of the brain that runs all the functions of your body. That is like a core memory system. (Forgive me, I’m not very savvy when it comes to computers).

You also have external hard drives
They hold information (Speech, abilities, people, learned academics and long time memories of places and people)

Then you have the cache, which retains temporary information. What you ate, where you went a week ago, and what appointments you have coming up and what I’m going to type right now. The cache helps things to flow easier so you have quicker access to certain things, like tapping into math skills, or the use of speech. But it is not long term memory. I think most of us use it to learn new things but it requires time and multiple times to use a new skill to retain it and store it in the external drive.

Most of us only use it the most to help store to our hard core memory when young because of our curious nature. As we age we lose curiosity and don’t make a real effort to learn new things. So it’s stored in a temporary file and not necessarily deleted but never properly placed so its like fragmented storage. We don’t have a defragger in our brain to organize it all once a week or month, so it sits like garbage somewhere.
Then there is aging. Where like a computer, things get damaged and not repaired as quickly, until we have a hard time even using the cache.

Since it includes the capacity for unconscious thought, then by definition, it’s impossible to be filled…ever.

As hyperthymesia is real and some people can remember most of their lives in perfect detail it seems it isn’t possible for the brain to be full.
