I mean first you have to decide what a thought actually is. And then do you believe every single thought is stored in the brain? Where and how are they stored?
Biologically speaking, what makes every thought we have unique, like snowflakes? No two thoughts are the same, or are they? Is it possible to have two of the same thought? How would you know if it’s the same one?
(This is from what little I remember of college bio)
When you create a thought, from what little people know of it, it is a chain of firing electrons that shoot off and access different parts of the brain like the visual center and olfactory (smell) center. Then it stays in your short term memory while you do whatever needs to be done about the thought. If you think about it often enough or long enough, it eventually goes into your long term memory and you sort of keep it. But the structure of a thought really isn’t understood well.
They used to think that memory or thoughts were set in stone. But now they know that every time you access a memory, you modify it a little. Yet some people have eidetic memory (photographic memory) and can remember almost everything from a visual experience perfectly, so who knows. Maybe every thing you’ve ever experienced is somewhere in your brain. But I am not sure about that because it would be a lot of wasted use of resources. Proper use of resources is key to evolution and creatures are not often created that waste energy unnecessarily.
What they call deja vu, which is more frequent with people with schizophrenia, is when you notice the same thing happening over time or if you notice you have a thought that you’ve had years ago. But often, it is not true.
I think a thought can make the most sense if you look at the abstract of what a dream is.
You have a bunch of old stimuli in the mind that left things active and not fully processed. You also have a lot of learned organization skills and a sense of a timeframe… you’ve plotted out your whole day or at least know what to expect. You have the list of things that you or others might want you to do… you have all the factors that are tied into the environment and the construct of you ongoing self.
That’s the context of thinking. They’re actually limiting factors that constrain and narrow your thoughts to a realm of topicality… then you have the validity of the thoughts that transpire and the invalidity… the jostle of confusion.
Insight and intuition are factors…
I mean you have to look at the brain physiologically if you want to understand them. We are a mental experience… but the mind is very much just an electrochemical system of neural networks. It’s more of a computer… except it’s fleshy and underpinning most human motives are biological and even neurological needs. Even a negative mood seeking a positive train of thoughts to induce a chemical fix due to dopamine and adrenaline being released… Regarding neuro though they refer to adrenaline as epinephrine… the epi-pen… the adrenaline shot for allergies.
A thought itself can be seen from two sides… the outside and how it manifests… and then from the inside regarding the experience of having the thought and knowing it’s after effects.
There are different forms of thinking as well. Regarding linguistic thinking or the internal monologue… I consider any repitition of words the same thought. Though they might stem from different context a and even have different effects.
You should seek out a crash course in neurological cognition. Serotonin and Taurine do a lot to keep a brain at it’s best and with most access to itself… It’s all very comlicated… but basically you’re looking at neurons hooked up in all sorts of 3 dimensional circuits that can communicate with sensitivity… not just absolute A to B… but A can send a half signal to B
Basically the mechnics of a singular thought are beyond modern sciences capacity to pinpoint however they have divided the whole brain up into different regions that are known for doing certain things…
Schizophrenia is a megaplex of corrupt wiring in the head… In most cases it’s cerebral and deals most with realms of higher thinking… left and right heispheres… not the underlying r complex which deals with more instinctual motivations and autonomous motor control… most of that is left in tact and unaffected by schizophrenia.
The sense I made from that is that when an experience is getting written to memory the brain accidentally does it twice… which gives you the sense that you’ve experienced it before…
The effects on the body are neat though… like kind of a heart sink.
