Inspirational quotes with neocortex.
. . . waves of desert heat . . . I must’ve passed out, because when I woke up I was shivering and stars wheeled above a purple horizon. . . . Then the sun came up, casting long shadows. . . . I heard a vehicle coming. Something coming from far away, gradually growing louder. There was the sound of an engine, rocks under tires. . . . Finally it reached me, the door opened, and Dirk Bickle stepped out. . . .But anyway so Bickle said, “Miracles, Luke. Miracles were once the means to convince people to abandon reason for faith. But the miracles stopped during the rise of the neocortex and its industrial revolution. Tell me, if I could show you one miracle, would you come with me and join Mr. Kirkpatrick?”I passed out again, and came to. He was still crouching beside me. He stood up, walked over to the battered refrigerator, and opened the door. Vapor poured out and I saw it was stocked with food. Bickle hunted around a bit, found something wrapped in paper, and took a bottle of beer from the door. Then he closed the fridge, sat down on the old tire, and unwrapped what looked like a turkey sandwich.He said, “You could explain the fridge a few ways. One, there’s some hidden outlet, probably buried in the sand, that leads to a power source far away. I figure there’d have to be at least twenty miles of cable involved before it connected to the grid. That’s a lot of extension cord. Or, this fridge has some kind of secret battery system. If the empirical details didn’t bear this out, if you thoroughly studied the refrigerator and found neither a connection to a distant power source nor a battery, you might still argue that the fridge had some super-insulation capabilities and that the food inside had been able to stay cold since it was dragged out here. But say this explanation didn’t pan out either, and you observed the fridge staying the same temperature week after week while you opened and closed it. Then you’d start to wonder if it was powered by some technology beyond your comprehension. But pretty soon you’d notice something else about this refrigerator. The fact that it never runs out of food. Then you’d start to wonder if somehow it didn’t get restocked while you slept. But you’d realize that it replenished itself all the time, not just while you were sleeping. All this time, you’d keep eating from it. It would keep you alive out here in the middle of nowhere. And because of its mystery you’d begin to hate and fear it, and yet still it would feed you. Even though you couldn’t explain it, you’d still need it. And you’d assume that you simply didn’t understand the technology, rather than ascribe to it some kind of metaphysical power. You wouldn’t place your faith in the hands of some unknowable god. You’d place it in the technology itself. Finally, in frustration, you’d come to realize you’d exhausted your rationality and the only sensible thing to do would be to praise the mystery. You’d worship its bottles of Corona and jars of pickled beets. You’d make up prayers to the meats drawer and sing about its light bulb. And you’d start to accept the mystery as the one undeniable thing about it. That, or you’d grow so frustrated you’d push it off this cliff.”“Is Mr. Kirkpatrick real?” I asked.After a long gulp of beer, Bickle said, “That’s the neocortex talking again.
There is another connection between infancy and dreams: both are followed by amnesia. When we emerge from either state, we have great difficulty remembering what we have experienced. In both cases, I would suggest, the left hemisphere of the neocortex, which is responsible for analyticrecollection, has been functioning ineffectively.
It is interesting that it is not the getting of any sort of knowledge that God has forbidden, but, specifically, the knowledge of the difference between good and evil-that is, abstract and moral judgments, which, if they reside anywhere, reside in the neocortex.
I believe consciousness is simply what it feels like to have a neocortex.
Recall the metaphor I used in chapter 4 relating the random movements of molecules in a gas to the random movements of evolutionary change. Molecules in a gas move randomly with no apparent sense of direction. Despite this, virtually every molecule in a gas in a beaker, given sufficient time, will leave the beaker. I noted that this provides a perspective on an important question concerning the evolution of intelligence. Like molecules in a gas, evolutionary changes also move every which way with no apparent direction. Yet we nonetheless see a movement toward greater complexity and greater intelligence, indeed to evolution’s supreme achievement of evolving a neocortex capable of hierarchical thinking. So we are able to gain an insightinto how an apparently purposeless and directionless process can achieve an apparently purposeful result in one field (biological evolution) by looking at another field (thermodynamics).
These computer simulations try only to duplicate the interactions between the cortex and the thalamus. Huge chunks of the brain are therefore missing. Dr. [Dharmendra] Modha understands the enormity of his project. His ambitious research has allowed him to estimate what it would take to create a working model of the entire human brain, and not just a portion or a pale version of it, complete with all parts of the neocortex and connections to the senses. He envisions using not just a single Blue Gene computer [with over a hundred thousand processors and terabytes of RAM] but thousands of them, which would fill up not just a room but an entire city block. The energy consumption would be so great that you would need a thousand-megawatt nuclear power plant to generate all the electricity. And then, to cool off this monstrous computer so it wouldn't melt, you would need to divert a river and send it through the computer circuits.It is remarkable that a gigantic, city-size computer is required to simulate a piece of human tissue that weighs three pounds, fits inside your skull, raises your body temperature by only a few degrees, uses twenty watts of power, and needs only a few hamburgers to keep it going.
The neocortex is not like a computer, parallel or otherwise. Instead of computing answers to problems the neocortex uses stored memories to solve problems and produce behavior.
When we are experience shame we are often thrown into crisis mode...In this mode, the neocortex is bypassed and our acess to advanced, rational, calm thinking and processing of emotion all but disappears...we find ourselves becoming aggressive, wanting to run and hide and feeling paralyzed...
