Stochastic firing of neurons. The brain is very noisy.

Somebody staring at peanut butter accidently had the neuron that coded for chocolate activate and here we all are.

Not all ideas are created through randomness.
Some ideas are very elaborate and specific and intentional.
How do you explain them.

>The brain is very noisy.

I have psychotic episodes where I start to hear the neurons in my brain firing. Like whatever auditory neurons in my brain is supposed to hear, is hearing shit it's not supposed to. It's absolutely defining and frighting, like an ocean of chaos.

>>6526202
The idea is that the underlying process is chaotic even if the result seems totally deterministic. For example when collecting visual data there are many possible interpretations, your brain settles on the most likely interpretation but the process is chaotic enough that you can take another look at something and interpret it differently. See optical illusions.

Clearly they are beamed into us by a hyperdimensional God-like entity.

>>6526214
Auditory hallucinations are a sign of psychosis, please seek psychiatric care if these symptoms persist.

Your genes wires your brains under optimal conditions on certain ways. The ways these happen defines the recording patterns of your memory. The recording patterns of your memories defines how they are read. Reading memory is essentialy association. So when new associations happen in billions these cases, they may have never been formalised and recorded. Thus, the new associations are stored with a pleasure feel and will be reviewed with all you can remember of. If it passes this, I call it longterm cognition, then another wave of pleasures follows and the stress of it wears off. So it becomes a source of happiness itself, leads to confidence, confidence leads towards writing it and spreading it and the after all it is recorded for the public or a group of people. Taking a shortcut on this is common and less exciting, either a desperate or materialistic act. The goal of the conscious brain is to reduce stress for mankind by deep solid cognition.

Are you a neuroscience student?

>>6526220
Well sure, the brain is a parallel and stochastic.
But for some reason I think having accidental ideas and intentional ones have different underlying neuronal mechanism.

>>6526237
No.

>>6526232
Where did you read these things? You sound very sure.

>>6526220
I don't actually believe that the stochasticity of the brain plays any central role in its function. There are people who think that it can be some kind of "deal breaker", forcing a resolution to, say, a donkey equidistant from two equal rewards. But that seems like a load of hooey to me.

The idea that just because our brains are computers and computers act deterministically then we must also act deterministically seems like nonsense. You can get chaotic results out of any complex system without needing to introduce some element of dice rolling.

He very clearly pulled them out of his ass.

>>6526256
I encourage pessimistic overview, so keep it up 200%.

>>6526243
Interest + Internet lead me to these lexts and images wherever were they, amirite? Have you seen a dissected brain? I laugh at wikipedia, but you sure can start there. You can listen to neuroscience talks twice a day. It builds up if you are interested.

Usually novel ideas forms by crossbreeding and combining old ideas and identifying a patterns that make a connection that makes sense to us.
It's not surprising we come to do this in the abstract seeing how the same thing is something we do all of the time to make sense of the world around us.
If we come across a scene in the environment we look at the signs available and from there extrapolate using our experience to gain a clue to what's going on.

When you have a novel thought it's like a ghestalt shift that let you see something already familiar from a new perspective you hadn't considered before.
Neurologically this is explained by your neurons making new connections physically inside your brain, connections that is stimulated often will continue
to branch out and grow more permanent, while connections that don't end up getting used often will dissolve.

Thank god

What exactly is an example of a "new idea"?

>>6526251
Well
>brains are computers

That's why it doesn't make sense to you. You're using a flawed premise.

>>6526442
Well what is it then, EXPERT NEUROSCIENTIST??

>>6526460
That's not how analogies work.
Some people take it too far.

>>6526471
I'm sure they do but that the brain operates as some kind of I/O device with memory is undeniable.

>>6526480
It's a type of confirmation bias.
You search and over-focus on the similar functions.
No matter how far you go, it's still an analogy.
You can make analogies for pretty much anything if you're in the mood.

Computers and brains share alot of things, sure, as you say there's no denying that.
Although taking the analogy out of context to speculate and extend your conjectures is not wise.

>>6526518
What functions does the brain possess that cannot be replicated in simuli? Not sure what you're trying to say here.

>>6526534
In my opinion computers can theoretically replicate everything the brain does.
Thing is, computers can replicate almost anything with enough computational power and the correct algorithms, but that's not the point.

What I'm not agreeing is the direct comparison of a brain and a computer as functional systems.
The computer can also replicate my dick, doesn't that a computer is like my dick.

It's just annoying watching people taking the analogy at heart and waving it like it's a synonym.

>>6526556
I guess I see what you mean. It's troubling when someone asks what the equivalent of RAM in the brain is.

I guess I meant more that the brain functions according to some particular set of algorithms (your dick does too, in a way), but we've gotten rather aside the point.
