Is it possible for a glaucoma patient to recover spontaneously?

I am 29 years old and I have never played any sports before but I have been interested in sports for several days. I am 183 cm tall and I hate my height. I am very envious of people who are over 190 cm tall at the age of 17. How many centimeters could I gain maximum? I read various articles and wrote that it must be forever. What’s the truth? Is there any cheap way (I am unemployed) to maximize my height? Is there any free and possibly cheapest way? (I’m unemployed)? Don’t reply this type that nothing can be done or that I accept my height?

I am interested in the possibility of uploading information to the brain like in The Matrix. To that end, I’ve been studying the brain and trying to understand how memories work. Unfortunately, I’ve hit a wall. I have a basic understanding of the structure and function of neurons. I understand that memories are stored in the brain as cellular assemblies formed by the hippocampus. I also understand that memories are not stored in any particular region of the brain, but are stored across the entire cerebral cortex. I know that the temporal lobes become enlarged in people who memorize a lot of information due to the accumulation of cellular assemblies. What I don’t…

There are people like Terence Tao, Ed Witten, Grigori Perelman, Lennard Ng and probably 1000s of others areound the world who are super smart. Any clues of what distinguishes their brains from the brain of an average person from the street? There is some degree of correlation between intelligence and cortical thickness as well as brain volume. What else?

Is it true that bicarbonate binds reversibly to the heme moiety of hemoglobin? Or do the heme portion only bind oxygen?

We know there are inhibitory projections from PFC to the amygdala which calms it and extinguishes anxiety/fear/anger etc. But there are also bidirectional projections between PFC and amygdala. What do they do?

This is not easy to explain, and every time I do I get looked at like I'm either an alien or talking bollocks I have the ability to move something inside my ears that causes a hum and a vibration. The sound reminds me of the way wind sometimes sounds through the phone, and it tickles a little bit. It happens exclusively when I want it to, and I get tired after about a minute. The intensity is affected by my breathing, but it can be done while holding my breath with either full or empty lungs. After a minute or two I get tired. I learned to do this when I was trying to learn to move my ears like some people are able to I would appreciate any clues as to the under…

Which parts of the brain are responsible for predicting consequences ofactions? Dysfunction of what parts can cause disturbances to this ability? Like dangerous behavior or careless heath related behavrioe?

What brain regions/network are involved in disgust recognition? Like, the ones that make you feel revulsion while touching one's poop or any other similarily disgusting stuff?

Anyone doing research on deep learning models for classification of Alzheimer's? I am trying to understand the dataset Oasis-3 and unable to find the labels or classes of the given images? Please guide

Hello I just want to ask about something weird I've noticed... just out of my own curiosity^^ Apparently I have the ability to perceive some 2D images as 3D... very clearly 2D images that are not meant to be perceived as anything but 2D. It really only happens when strong colours collide... black on pure red, for example. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQeUhbTReL-MrEEnjGCB1N_7NHUNk3Tc4zYBtKjZMWiZd1n8vVKIA <--This image here is the most '3D' picture I've ever seen... I cannot not perceive it as 3D. I showed the same picture to some friends, though, and they said they couldn't see anything even remotely 3D about it. I can't come up with anythin…

This is from a person who spends several hours a day word-processing in a smallish upstairs boxroom (2.4m x 3.8m) that faces south-west. The room is centrally heated (20 C) and efficiently double-glazed. For sometime now I have suffered from minor, but persistent respiratory problems, stuffy nose, throat-clearing issues. I also have chronic sinusitis, which I plan to do something about just as soon as Covid-19 finally abates. . . whenever that might be? Meanwhile, these respiratory problems have all but vanished since using a humidifier. It seems that it more than compensates for the room's dryness, which may be due in large part to running two PCs, plus a UPS batte…

It all began 20 years ago when I decided it might be fun to understand how Consciousness occurs in the Brain. I decided that Conscious sensory perception, specifically Light and Sound, were the things I would study. I can see Light and I can hear Sound. I eventually narrowed my studies to the Visual Experience. The thinking was that if I could understand more and more how the physical Brain, Eye and Ear actually worked then the Conscious perception of Light and Sound would become obvious. That was naïve. The Brain Physiologists have become pretty good at finding the Neural Correlates of Consciousness but they have hit a brick wall beyond that. Unfortunately, that was my c…

This theoretical formula is based on Arnold Ehret's work from I believe around a hundred years ago? Arnold Ehret was a dietetic practitioner who stated the following, but not formulaic. I need to know if it's the right format: Human wellness (physical and mental) is measured as follows: the degree of direct work output and maintenance of full stamina against the inverse proportion of foods and substances consumed and the mitigation if any, of fatigue. How might it be better formed?

Cryonics is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of a human corpse or severed head, with the speculative hope that people will be able to be revived through advanced biotechnology in the future. Is this procedure possible and is there any reason to believe that it will be possible to revive people who were cryopreserved ?

Im correcting some old tests in physiology and came upon the question "Which statements characterize IgM immunoglobulins" One of the alternatives are "it’s a secretory immunoglobulin". Is this correct? I know that the main secretory immunoglobulin is IgA (sIgA) but I found some sources that mention sIgM, though it's not as effective as sIgA. Is it considered a secretory immunoglobulin?

The time for visual persistence is typically taken as 1/30th of a second; what is the minimal time a light should be on to recognize its brief presence ? Example, a high speed mechanical shutter wheel in front of a light source. (Or a pulse on LED) The light passes a slot to the eye for one millisecond. Probable visible. What if one microsecond ? Would that time be long enough to be detected by the eye ? Is there a name for that 'time sensitivity' ?

Plead ignorance at this stage in my life but how dods this process happen in the body? When I eat my meal there are both liquids and solids. Clearly they are separated somehow.Does this occur in the stomach? There can't be a Trump recommended centrifuge down there so how does the process get started (are there a few stages ,perhaps?)

I've no experience or training in this expertise area so please forgive if I don't seem to explain things quite right. Within the last few months I without warning got a sharp pain that just appeared in the right hand side of my chest and slowly seemed to moved down my body towards my stomach, but then disappeared for a short while before returning. The pain appears from the inside of my rib cage on the right hand side now just below my chest area to the side. After a nights sleep the pain is not present the following day until about lunch time or afternoon, and it seems depending how I move my body around will either cause the pain or stop the pain, hence standing a…

Has anyone ever been found to have more than one of these in each knee? Allowing their knee to bend slightly inwards in a bow shape?

Hey there. I’ve held the pen weird ever since I was a kid, and a few years ago I noticed that I’m missing a joint in my thumb. Both thumbs, actually. It’s the basal joint. There’s no pain or anything, perfectly functional (except people text faster than me), and my sister has it, too. I’ve searched the internet but can’t really find anything conclusive. Any ideas? thanks in advance! cheers, max

I have brain damage to my basal ganglia referred to as "face of giant panda." Is this reversible?

I heard that relapse can happen if you don't practice, right?

The velocity at which an electrical signal propagates down an axon is determined, in part, by the thickness of the axon. Then we can expect that after holding all other factors equal, people with thicker axons process information faster. It wouldn't surprise me if there was significant variation in this trait, since the lower caloric expenditure associated with thinner axons and slower propagation of electrical signals could be helpful in environments where food is scarce, or where gestation and maturation needs to occur quickly. I can go to the gym to increase the size of my muscles, so is there any way to increase the thickness of my axons?

So i had a thought, (most if them are dumb, this one may be too) if someone makes Lab grown bones in the shape of "devil" horns, would it be possible to attach it to their skull? Just to put there, not to grow or anything. Im guessing there's a lot of things wrong with that, but I was curious of if it would be possible. Also, could there be a possibility part of the bone could be left showing, and it be attached around the bottom to make it look more like actual horns. Would the body reject them? And what complications could arrive, or are there too many to count?
