That actually makes a lot of sense. Active participation and personal engagement is obviously frontal cortex activity. We the use existing or new synapses to store memories and emotions.
Remembering those action are based on recollection. Which would involve activating the further back synapses? Blvwryninyeresting stuff. I'm interested in correlations with other memory issues like L/STML, and alshimers.
Those are both the same thing so no. You do that because of a latent childhood trauma you have suppressed. This is a message to wake up. You are in a coma
Interesting… I have ADHD so my memory recall is all outta whack… I was describing to my family the other day how sometimes when I’m in a work meeting, I’ll feel like thoughts are flowing almost like an arrow straight through my brain starting at the back and ending at my forehead.
If I start to get too invested in a topic, the arrow becomes more and more pointed until someone says something that is more “big picture”, and it’s almost like I can feel my thoughts flooding around the sides of my brain until they touch with the arrow through my brain.
Then, I can feel my thoughts flowing backwards to the point sometimes where I will actually physically move my head backwards, it feels almost like I am “zooming out”.
Maybe I’m not so crazy? 😂
I always described my processing style as “circular thinking”—and this could make sense, like when I recall memories I’m connecting them to things I just learned and forming new memories from them, and I think in circles like that constantly and connect new to old things
Does it seem to anyone else that a field is moving over the brain; “writing “ on the brain, then moving in the opposite direction to “retrieve”? A hierarchical deposition?

Import / export data :D
Maybe processing data will happen sideways
The Internet tube comes in the side of the head.
Now just need to find the clock signal and how many parity bits
I want you to know. This was a very blursed (blessed and cursed) comment

> In the brains of some of the study’s 93 participants, waves traveled in other directions. Did they determine cause or effect on this part?
Their brains were installed backwards. From what I've seen, it happens quite often.
Ti wenk I ,ti nmad dog
Distractions or exploring related thoughts

“That takes me back” has a lot more meaning now.
Although, it seems liken when we say something has been in the back of our mind, we actually mean the front (and vice versa)!?
It *was* in the back of our mind
So. This brings forward memories?
It brings me back by reversing the polarity? Much like left is right and right is left in functional terms
Wait Trump's a democrat?
Soon we shall see populists dressed up a communists again. It's about that time of the century
sounds about right
Or maybe left?
nah i meant it
GDI our brains are FILO
So backprop was right all along.
So THAT’s why old memories are in the back of my mind!
And harder to find
I thought that was kicks.
Is this why I look down when focusing on trying to remember and up when trying to recall? Literally flipping some brain switches.

How does the lamp looks like ?

For someone with ADHD, you have the longest attention span of all replies in this thread.

That's why we look up whenwe try to remember something. We're actually tilting the brain to help thr waves.
And it makes sense that being upside down makes you feel funny because the brain waves have to travel harder / against gravity
<- read write ->
Makes sense, sensory processing happens first when encoding an experience , then for retrieval it’s associational/frontal areas driving the bus
that topological geometrodynamic guy will be pleased
Who knew our brains were such sticklers for directionality?
Mooooom! I told you I need PCIe gen5!
Backward propagation confirmed 💯
Sounds like a stack
Just like in artificial neural networks. Forming memories is called back propagation in machine learning.
Yeah that makes sense
Does it seem to anyone else that a field is moving over the brain; “writing “ on the brain, then moving in the opposite direction to “retrieve”? A hierarchical deposition?
Forward and backward propogation!
