Sometimes we have flashback memories of something we haven't thought about in years.  Is the brain just selecting random memories to show us, from its vast storehouse of memories?  How big is that storehouse?  Does it include everything we've ever experienced?  Deeds, emotions, images, sounds, smells...everything?

Yes. If not, how would we be able to recall these things? They must be in there somewhere even though we might not be consciously aware of it.

Seems to be unclear at the time.
But we do remember more than what we can trivially access.

That's sort of a "does a falling tree make a noise if no one's around to hear it" kind of question.

I guess the memories are all in there somewhere, but if we can't recall them, then they might as well not be in there.

The brain registers a lot more than you perceive, same with memories.
There's different kinds of memory - implicit/explicit or conscious and unconscious
Or repressed.

We don't know how ever if the brain keeps EVERYTHING since science hardly ever is about absolutes.

It sure "remembers" a lot more than you do.

I think when you experience something, it almost instantly becomes a memory. Depending on how strong the connections created at that moment and later connections, reinforcing connections would lead them to become long term permanent. Maybe short term ones become dormant but further similar connections can awaken them. Retrieval can be tricky sometimes depending on amount, strength/pathways....

I'm sure some experiences pass/wither/die. Also wiring, injuries, disease etc.., can play a part.

Just a theory, my memory can be really really bad! smile.

Edited: Sometimes the more senses used the stronger the memory. Smell is one of the first ones from birth from what i remember, that's why i don't like hospitals smile.

Including, unfortunately, things which it made up.

How many humongabytes is the brain's capacity?  Imagine 5 minutes in a life.  The brain experiences input that is visual, aural, tactical, olfactory, etc.  Can the brain store all of that?  Now, imagine 30 years.

The brain's memory storage capacity is estimated to be at 2.5 petabytes, but since there's not a definitive idea of how memory is stored and accessed, with some memories being complex or detailed, other memories being fairly simple, there's no way currently to know for sure. It seems pretty clear that some memories are discarded and make room for more. And as noted, our memories can be subject to change. Even if we do remember everything, it won't necessarily be accurate memories.

From the point of view of someone with a brain injury, me. I often wonder how my long term memory works so well. And my short term memory. Not so much. I am forty seven years old. And I can remember things from my childhood, good and bad, like it happened yesterday. I can recall names of old childhood friends I've not seen in decades.

I can tell you that I learn differently from "the norm". Once I learn something, it's there. It's just a matter of recall. There have been times when I struggle to remember something. And then I just give up. And all of a sudden, bam! People that don't know me, or my struggles, get mad, sometimes. I don't talk about it often. And in some cases I don't talk about it nearly enough. I was born hydrochephalic. Commonly known as "water on the brain".   Steve

I know childhood phone numbers that I haven't dialed since I was about 11 yrs old.

Yet it took me nearly 2 yrs to memorize my own cell # and my husbands. I even still get stumped on them sometimes. My short term memory sucks.

I hear that.  TBI's suck.  Which brings up an interesting point - amnesia.  In the case of my brain injury, I suffered total amnesia of the incident (which, logically thinking, is probably a very good thing, although it drives me insane at times).  Some people eventually recover amnesic memories, while others never do.

For those who never do (which they suspect I'll be in), are our brains that successful at quarantining off the memory, despite repeated efforts to remember it?  Or, in an attempt to prevent the rest of the mind from ever remembering it, did that portion of the brain simply opt to NOT retain the information?  Is that part of my life really 100%, completely forgotten?

(After typing that, and having thought about that possibility for the first time, it's extremely scary, and more than a little depressing.)

Actually, Hyperthymesia is a real condition shared by a couple hundred people in the world, where they can remember details from their every day life for decades.  The actress Marilou Henner (from the TV show "Taxi") has this condition.

I suspect that it is nothing like the "Unforgettable" character, played by Poppy Montgomery.  Still it's pretty interesting, and gives credence to the possibility of the brain to remember "everything".

How many people still memorize phone numbers now that our phones do it for us?  I remember every phone number I have had and those of friends and family up until the smart phone age. There are people I talk to and text regularly, but I couldn't tell you their phone numbers for love or money.

On the other end of the memory spectrum, my earliest memory is of the night my sister, Loretta, was born - I was three at the time.  Mom didn't make it to the hospital, so "Cousin Pauline", a retired midwife who lived in the neighborhood, handled things. There was a lot of excitement going on in the house and my grandmother would not allow me to go into my parent's bedroom, which seemed to me to be the center of activity.  While "Cousin Pauline" was leaving, I managed to sneak in and have a peek at what was going on.  Mom was holding my brand new sister, and having never seen a red, squishy looking newborn before, I considered her the ugliest thing I had ever seen before!

I lean toward believing our brains can store truly awesome amounts of memory; it's our conscious minds that can only access tiny bits at a time.

From what I know about the topic (which isn't a lot) the synapses in our brains create links through biochemical electrical impulses.

Its the strength of these impulses and the rejuvenation of them that create strong memories, along with linking to other parts of the brain for support, sensory input.

Over time these links can weaken and degenerate if not reinforced, so in short no we do not remember everything.

Not sure how accurate my science is, going on memory here..

Except for my ex-wife who just won't let it go... wink

Infinite storage space.

Recalling information is the part that evolution hasn't done very well at.  Then again, maybe not remembering some things is mean to protect us.

It's very highly compressed.  Think JPGs saved a 1...except the brain can do 0.000000001

That's probably why some memories are messed up.  It's not a good compression method.

One of my first ever combination locks.  if you were to ask me what the combo was, I could not tell you.  But I wouldn't be surprised that if you could actually locate that lock and put it in my hands, that I'd suddenly figure it out within a couple tries.  That's what happened MANY years ago. A lot I hadn't used in probably 5 years...I found it...unlocked it. Have no idea what I did with it...but I remember having no clue as to how to open it but after trying a couple numbers it unlocked...I'd say that time, I was in my early 20s and that was a lock I had used back in Jr. High.

I have some very detailed memories from about age 4.  Maybe earlier...I don't know.  But I can still recall the swishing sound the plastic covering over my cloth diaper made when I ran to the front door to greet my older brother's friend Gary.  That would put me at what...age 2? 3?  when do kids typically get potty trained?  My other earliest memory would be my mom washing my diaper in a toilet...well...washing what I would presume to be the poop out...then probably rinsed as best as possible before putting into a regular washer.  But I can still see my mom sloshing it around in the toilet.  eew...gross memory!!

I believe that is the earliest I can remember.  all of my other vivid memories are likely 4 and older.

This is just my thinking, but the way I think the brain works is that is really doesn't remember details that well at all, or raw data.

What I think it does is store abstract data, like the image of a summer sky on a particular day, we don't really remember the exact details what we remember is an amalgamation of all of the inputs we have ever had to create that image in our heads.

We know sky, we know blue, and clouds...so we put together memories in real time based upon probably separate sources of information.

I don't think our brains have the capacity to store that much information over a lifetime of living especially as we age I think the memories become more abstract and less defined, call it data rot..

I can remember what my wife looks like and could recognize her in a crowd of similar faces, but could I recall her facial details if she weren't standing in front of me, probably not.
