hiddeneagle98 said:Think about dendritic trees as the actual heavy lifters of computation within the brain. They aren't just passive wires passing signals along; they are incredibly complex processing hubs that perform all sorts of sophisticated operations on incoming signals. We’re talking about everything from basic multiplication and addition to subtraction, and even more advanced logic like XOR gates. It's much more active than most people realize.

Initially, actin and microtubule filaments are arranged in a somewhat symmetrical fashion. From this arrangement, neurites—those cellular extensions—begin to develop, featuring a microtubule-based trunk and an actin-rich tip, with these structures overlapping within the transition zone.
Actin filaments tend to push microtubules toward the center of the cell, though we can actually track cytoskeleton components in living cells by using genetically engineered fusions with fluorescent proteins. Once that's done, the dynamic reorganization of these parts can be observed through subsequent video microscopy studies. In these observations, you start to notice a constant flow of actin filaments moving from the cell's edge toward its center, a phenomenon known as retrograde flow. This movement is driven by actin polymerization at the outermost edge of the cell, which is then amplified by the action of the molecular motor myosin. This retrograde actin flow can also shift microtubules toward the interior of the cell once they enter the actin-rich outer regions. The force transmitted by this retrograde flow leads to the compression of microtubules, causing them to bend. This suggests that actin filaments can directly influence how microtubules are organized. Conversely, microtubules can also exert influence back onto the actin filaments; for instance, a cluster of microtubules might restrict the spatial distribution of actin fibers. However, it remains unclear exactly which property of the microtubules is driving this effect on the actin cytoskeleton. Could microtubules be generating local chemical signals that alter actin dynamics? Or perhaps the mechanical stability of the microtubules simply limits the actin flow through a more passive mechanism? There's also the possibility that microtubules play a more active role, where molecular motor proteins push against the retrograde flow, creating a sort of tug-of-war. As long as neither force gains the upper hand, changes in the cytoskeleton's organization and the overall shape of the cell remain minimal.
Perhaps you were referring to their specific role in data processing?
Is there actually some kind of lingering doubt about whether I was talking about "data processing"? Seriously?
I’m honestly not quite sure what you're getting at with all these exhaustive, hyper-detailed descriptions of what you're seeing under the microscope.
When I brought up neural structures earlier, I wasn't just throwing random science terms at the wall; I was trying to bridge the gap to that whole "panpsychism" thread we've been circling. My line of thinking goes like this: if you look at those incredibly complex architectures within the brain and try to calculate how particles move through them—basically how they interact with the fundamental fabric of the universe—you eventually land right back at the doorstep of consciousness as we experience it. It’s all interconnected, and honestly, if you follow that logic to its conclusion, it fits perfectly under the umbrella of panpsychism.
So, here’s how I see it: consciousness is basically an emergent phenomenon arising from the very fabric of the universe—that underlying substrate that dictates how everything material actually moves and behaves. Honestly, we could probably get away with using the word "spirit" here too (though, Amanda Jackson5, please jump in and set me straight if I’m totally off base). If we go that route, then consciousness becomes this specific formation of a "universal spirit"—maybe even the Absolute—which gets triggered by a particular arrangement of matter. We're talking about the brain's physical structure and those specific electrochemical signals it generates. It’s like the universal spirit is using nature as its secondary vehicle to finally achieve self-awareness.
I think I’ll throw in one more little analogy just to make this easier to wrap your head around or visualize properly. Think about it like this: just as a tornado or a whirlwind is its own distinct, specific formation within the atmosphere, consciousness itself is a unique, specialized formation within the "cosmic spirit." In fact, if you really look at it, living beings are essentially just complex vortices—little swirling whirlwinds of existence, if you will. When you start looking at energy dissipation structures operating outside of equilibrium, things get incredibly messy, and honestly, that’s where the real science happens. Most textbook models want to pretend everything is sitting in a nice, predictable state of balance, but the real world doesn't work like that. It’s rarely static. It’s constantly being kicked, pushed, and shoved by external forces, and trying to model how a system sheds that excess energy when it isn't in a steady state is like trying to map out the exact path of a leaf caught in a Chicago windstorm. In a standard equilibrium setup, you can almost predict the decay. But once you step outside those boundaries—into that non-equilibrium territory—you’re dealing with systems that are actively resisting or reacting to constant flux. You have these complex dissipative structures that aren't just absorbing energy; they are organizing themselves around it. It reminds me of how a massive power grid like ConEd handles a sudden surge during a heatwave in New York; the system has to dissipate that massive influx of load through a series of complex, interconnected failsafes to prevent a total meltdown. If the structure isn't designed to handle that specific type of chaotic input, the whole thing collapses. The math gets heavy because you aren't just looking at simple entropy increases anymore. You're looking at how energy flows through a system to create order out of chaos, even if only temporarily. It’s a delicate dance between the driving force pushing the system away from stability and the internal mechanisms trying to bleed off that energy to keep the structure from tearing itself apart. It’s far more dynamic than the simplified versions they teach in intro physics, and frankly, it’s much more interesting to think about how these patterns emerge when everything is in constant motion.Look, there’s an endless mountain of material out there regarding that topic, and honestly, I was one of the first people to stumble right into it and get caught up in the whole mess.
