Rice on chessbord anecdote, bitches. Do you know it?

[mrbigdick No.2242362]

I've brought this up a few times now over the months, but it's probably one of the most awesome things I ever learned in my math degree.

Last year I took a course on mathematical biology and ecology , and one of the course texts was J.D Murray: Mathematical Biology (volume 2 I think)

The book has a whole chapter dedicated to a mathematical analysis of visual hallucinations.

The crux of the chapter was that there are only certain shapes you can actually see when visually hallucinating (swirls, spirals, stripes, and a few others I cannot really remember) due to the fact that visual hallucinations are conformal mappings from your visual cortex ( a 2D surface) via your retina and into 3D space.

For anyone who's ever tripped balls, it's pretty mind blowing.
Even to think that some mathematician has sat down, dropped acid and tried to jot down exactly what's going on in a rigorous way is pretty mindblowing in itself.

I recently went to a seminar (I cannot remember the guy's name now and it's killing me) from a guy who had been banned from researching (or maybe just teaching, cannot remember) narcotic induced hallucinations in the US so came to the UK.

His talk was awesome (bit too complex for my level though) and at one point he was describing the time distortion you experience on ketamine via bifurcation diagrams.

It's nice to know these people exist in the world.

Using deep brain recording (basically jabbing an electrode into the brain of a patient undergoing neurosurgery) researchers have found that neurons that fire before a person is aware that they have made a decision. In other words, anytime you arrive at a decision, your brain actually already decided to do that action and your conscious awareness of it is actually just your brain informing itself of what it just did. Some neuroscientists and philosophers have actually gone as far as to suggest that consciousness itself is not only an illusion, but a very under-utilized one at that. According to them, your brain processes most things very quickly on its own. When it encounters a problem (think in terms of a hung program on your computer) it then starts looping the information back over and over again and that's what you perceive as a thought.

Related to that, it's also worth noting that using the same technique, researchers have found neurons that respond to bizzarely specific stimuli. For example, in one man researchers found a "Simpsons neuron" which only became excited whenever the man saw, heard, or thought of anything related to The Simpsons.

>Jonas E. Salk (October 28, 1914 – June 23, 1995) was an American medical researcher and virologist, best known for his discovery and development of the first safe and effective polio vaccine. He stood out from his peers not just because of his academic prowess, but because he chose to do medical research instead of becoming a physician. Until 1955, when the Salk vaccine was introduced, polio was considered the most frightening public health problem of the post-war United States. Annual epidemics were increasingly devastating. The 1952 epidemic was the worst outbreak in the nation's history. Of nearly 58,000 cases reported that year, 3,145 people died and 21,269 were left with mild to disabling paralysis,with most of the victims children. When news of the vaccine's success was made public on April 12, 1955, Salk was hailed as a "miracle worker", and the day "almost became a national holiday." His sole focus had been to develop a safe and effective vaccine as rapidly as possible, with no interest in personal profit. When he was asked in a televised interview who owned the patent to the vaccine, Salk replied: "Well, the people I guess. There is no patent. Could you patent the sun? This is a development for the good of all mankind, not just for the personal gain of a single person, and because of that it belongs to nobody but the people. I'll simply give the cure to anyone who needs it."

There are smart drugs and true aphrodisiacs that have already been developed and reliably tested, that the FDA has refused to approve, or likely would if an application was completed.

The smart drugs had no significant side effects other than some headaches, while the aphrodisiacs would like have caused a small number of heart attacks.

New hallucinogens are being produced with a similar order-of-magnitude of potency to LSD. LSD only requires tens of MICROgrams to have hallucinogenic effects. Also, LSD has never been shown to cause brain damage, even when given in tenths of gram amounts, enough to produce prolonged hallucinations and likely produce PTSD-like effects.

On LSD, it produces visual "tunnel" hallucinations, because in the visual cortex, the vision is represented unequally. It is the case that the center of the eye has the largest proportion of tissue devoted to it, with the next outer parts of the eye having significantly less, with the pattern continuing. In terms of drug effects, the visual center is stimulated evenly, leading to more effect in the center of the visual field, because it is represented by more brain tissue.

On hallucinogens, the vast majority of tested hallucinogens have never been shown to cause structural abnormalities or brain damage.

Ketamine, a dissociative anesthetic that produces hallucinations, has frequently been found to cause a "near death experience", where one can sometimes see an all powerful being. An all powerful being changes from person to person though, with a Christian, it's a Christian god, with a Hindu, it's a Hindu god, and with children, superheroes have been documented as the hallucination's focus.

With a technology called repetitive transcranial magnetic stimulation, they can selectively excite or diminish activity in regions of the brain, safely and reliably, including completely disabling a person's ability to speak, which was the first test.

On the other end of the spectrum, a 1-2 milliamp current through brain tissue can reliably increase or decrease broad-region activity. Stimulating the motor cortex using an anode effect has shown it increases activity of the NMDA receptor, a key receptor in long-term memory and plasticity. It has also been shown to alter driving patterns, addiction tendencies, motor-skill learning speed, accuracy of memories, stroke recovery, and more.

Yes, I have the knowledge. I'm about to graduate with my BS in neuroscience. The issue is that the level of ignorance you spouted off requires going into several concepts to explain away, and I don't feel like writing a book to tell a random person on the internet why they're an idiot. That said, the very basic gist of why you're wrong is that neurotransmitters are not the end result of neural activity like you claim. Rather it's all about action potentials, the networks that neurons form, and the activity found within those networks. Your brain is also not "addicted" to any neurotransmitters. There's a level that has to be maintained, but that's true for every chemical in your body.

Even what I listed above is actually making things too simplistic, but like I said, I don't feel like typing up textbook chapters. If you want to learn more you can start off here: http://faculty.washington.edu/chudler/introb.html

The only thing that's usually happening near the speed of light is light.

Although the brain can and does use electrical connections in the brain/body, those would be more for transmitting an existing eletrical charge, while neurotransmitters are used for generating, modifying, or transmitting a signal in all other cases.

The brain is actually quite slow, it can just fire in a billion directions at once, and work on very little information.

I think one of the coolest things I read recently was Paul Dirac's prediction of antiparticles. I wish I could do it justice, but I'm a complete novice in quantum theory. It goes something like this.

Dirac predicted that there should be energy levels for electrons far below those that are normally observed. He asked, then, why don't the electrons we observe fall to those energy levels? He conjectured that perhaps this was because these energy levels did in fact exist and were already filled. He went on to say that if you could liberate an electron from this state, it would create a positively-charged "hole" in the state it previously occupied which was like it in every way. Hence, the electron-positron pair. When an electron and positron meet and annihilate, that is really just the electron jumping to a state with much lower energy, and the photons liberated sum in energy to give the energy difference between the electron before and after annihilation.

This part I really can't explain, but the reason I thought this was cool was because, for some reason, after I read that I felt like it was much more natural to conclude that particles should behave as waves rather than as classical objects, that what was in fact counter-intuitive to try to consider them as classical objects. It made me think that it's not that these things we call particles have properties similar to macroscopic waves, but that macroscopic waves have properties similar to particles.

Figured I'd I'd get something like that. ;) Any one in particular I should start with? I've never seen any of them.

I torrented them and they're audio only. I've seen a few videos of them on youtube but I don't know where to get them. Also, start at the beginning. Unless you're well-versed in physics, you won't understand the material so well if you start in the middle.

Total bullshit. I forget what the speed of your typical action potential in a mylenated neuron is, but it sure as fuck isn't anywhere close to the speed of fucking light, especially not when you take into account a network of neurons firing in sequence. IIRC the speed of an action potential (ie electrical charge traveling from one part of a neuron to another) is something like 54 MPH. It's actually very slow. Inside the brain the speed doesn't matter too much since everything is so closely packed together, but once you go into the peripheral nervous system the consequences of that slow speed become apparent. So much so that evolution saw it necessary to bypass the brain entirely in some cases in favor of spinal reflexes so that your body can actually, say, pull your hand out of a fire before you get 3rd degree burns.

You can definitely model that stuff mathematically. After all, the brain is just an organic processor. The issue though is that you're going to have a hell of a time modeling something as complex as a higher cognitive process considering the sheer amount of variables you would need to take into account as well as the need to essentially model the entire brain. Perhaps one day far into the future we'll be able to do that, but for now its an impossible task.

Still keeping it a personal insult as apposed to refutation. I call bull shit on your degree. Or you are just an idiot. Neurotransmitters are responsible for the flow of signals through the brain but for you to say someone is not addicted to neurotransmitters tells me you are a complete idiot or incomplete close minded. Heard of dopamine much? Pretty much every drug is designed similar molecular structure. You probably wont read this but if you do. Enjoy your "degree" if its real. And enjoy being a lab assistant for the rest of your uninspired life. Douchbag.

I believe some of the highest speeds on a mylenated neuron were around 100 km/h, I wouldn't trust this figure, however, as it is just me trying to recall a fact I heard about 6 months ago.

No one understands ethics.

No one understands causality.

Entropy is a mystery.

Depends how you define it, but sure.

> No one understands causality.
Probably true.

> Entropy is a mystery.
No. Entropy is just statistics applied to physical processes.

Black holes fit a finite mass into a point with 0 volume.
Density is defined as D=Mass/Volume

Black Holes divide by zero.

I guess to be more specific, causality and entropy are interdependent in a way that is poorly described. I see ethics as deeply based in the former concepts, but it's basically a stoicist notion which appears to carry little weight nowadays. Wisdom is clearly definable, so why the fuck is it thought to be so hard?

Also. Your muscles and joints report their position to the braiin. You're aware of where your body is even though you can neither see it nor feel it.
