Has anyone here ever had an EEG? I had one about 10 years ago and to this day the effects I saw during the EEG have stayed with me. It's very difficult to explain what I saw, multidimensional spheres? I really can't explain it. Has anyone else had these effects from an EEG and would it be dangerous to duplicate them just to further experience and understand the vision?

Dear Editor, Family vehicle Air Conditioning systems harbouring moulds, viruses and bacteria may account for 150 U.S. children per year, and 45 Canadian children per year potentially affected by lifelong paralysis through the new but already epidemic polio-like disease Acute Flaccid Myelitis (AFM), the Canadian rate being 1/155,000 in the affected 17 and under age group, not the 1/1,000,000 reported in some news articles. The U.S. rate is 1/490,000, that epidemic beginning in 2014, while AFM seems new in Canada. The disease pattern is: upper respiratory infection with high fever then sudden paralysis through spinal infection. Cases spike in August, t…

Can humans live without peripheral myelin, or is it just reduced peripheral myelin leading to disorders that is common?

I wanted to know, does my headache place indicates which part of the brain was too active or is too exhausted?

I was running a lap once, just running, until I had a thought. I started thinking about this show that I had watched, and all the different parts of it. I just kept on pointing out every detail in my mind, until that was all I could think about. The next thing I know, my alarm had gone off in my pocket, and I was breathing heavily. I didn’t understand what happened. Can you tell me?

I did a research for myself and basic principle is "tear and repair" the muscle for such building of muscle. now question is what is most EFFICIENT way to build such muscle with weight lifting, shall i lift heavy or lift light, shall i do many or small many thanks in advance

what causes skin aging like the sun I read on google saying it causes skin to age, what else beside time that cause aging many thanks

Can a person be muscular on the inside but the outer appearance of the body is not muscular? Also I remember when I was a kid in high school and we had rugby game against this other team, at that time weight around 220 pounds, and there was this skinny guy half my size and bony as hell (I could feel it when ever he tackled me) who seemed strong as hell for someone his size. Every time I ran at him he would lift me up with his strength and put me down, I don't know what the hell he was on but he was one hell of a kid. My second question is, why are some people who are skinny really strong for their size when they don't have muscles that show?

I read somewhere that humans only activate 30% of their muscles where as other animals like Chimpanzee have 100% activated which is why they are very strong pound for pound compared to humans. How to active my muscle fibers?

I am wondering if the stuff that I do in this life that causes epigenetic changes to occur in my body will be passed down to my offspring. Also I am wondering if working out and eating lots of nutrient dense food will help my offspring in terms of epigenetic changes. thank you in advance.

I find difficulty in understanding what the text want to say . i mean to discriminate two sources of light at a length of 10 meters we need them to be far from each other by 1.5 to 2 millimeters ... okay what if we want to see at further distance for example 1000 m or more ... i think the distance between the two sources shall differ .. I want to know what formula determines this and the second part of the text above is not really understandable for me ... i mean saying the fovea is less than 0.5 mm and this means that visual acuity is less than 2 degrees of the field ... i don't understand how ... so please if you can clarify it please do it or lead me to be…

Hi, I heard that the brains maximum capacity is equivalent to 4 terabytes of storage. But if this is true, then how can someone have an eidetic memory, I read somewhere that someone thought memory was stored in the 0. Field(as the result of an experiment where then taught a rat a trick, put its brain in a blender, put it back, and it still remembered the trick), could it be because of that, because if so that seems very practical bc an average brain can of course store only the 4 terabytes.

At what age is a person at peak performance? Such that they are at physically at their finest without lifting weights or exercise so the bodies natural peak state.

Also I am wondering if wetting my hair everyday will cause these natural oils from my hair to come off, or is that only if you shampoo it everyday?

I have just started playing cricket. But we I bowl my hand gets really painfull pins and needles. I believe that the virtual centripetal force during the delivery of the ball as my arm makes a 360 degree rotation forces the blood to flow into my hand causing pins and needles (you get the same feeling if you swing your arm in a circular fashion at high speeds) I have asked other bowlers whether they have this type of problem and they replied 'You get use to it'. Is there any way to stop the pain? (apart from getting used to it)

Is there a limit to perceived physical pain, with a point where the brain overloads and you simply stop perceiving it? or does it just go to infinity (theoretically)? For example, if someone were subjected to an alkali bath (google it) would they reach a point where they simply stop perceiving some (or all) of the pain perceptions? Can you die from your brain/nerves overloading on pain? What about other animals (non-human) or organisms that perceive pain?

In the literature, studies mention that the interstitial volume of a cell varies in each tissue of a human. Are there references from which one can obtain the values of interstitial volume in each tissue?

Hi, I would be very grateful if you would help me with the following question: What time does it take to decrease the HDL after an infection? thanks in advance, Nilrem

I'm not very aware of diving ... So what i understood from this text ... is that if you dive undersea for an hour at depth of 190 feet ... you need to ascend to the sea level gradually for 3 hours to avoid decompression sickness hazards ? and this schedule in the text ... means that the divers should wait for 10 minutes when he ascend to 50 feet then 17 mins wait at the 40 feet and so on ? Am i right or wrong ... if wrong please clarify it to me ... & thank you

I'm reading this article https://medicalxpress.com/news/2018-08-scientists-kind-human-brain-cell.html and I hit on this part This notion that consciousness is uniquely human is one I've heard expressed many times, though usually in more philosophical discussions of consciousness and it's always seemed to be just a guess people make based on intuition. This is a more scientific article (although it again seems that the writer is just guessing), so it made me wonder - is there some scientific reason to believe consciousness is unique to humans?

Hi, Can someone plz give me a list of which proteins are used for energy, in what food you can consume them and which of the proteins give most energy. Can someone also give me a list of proteins used for muscle growth and the ones that are most efficient of those.

What is the neurophysiologic mechanism which stands behind the tolerance? For example, if we offer a good cake to a person who didn't eat any confectionary for a while, majority of people will find it tasty. However, if we will feed the same person with a good cake every day, majority of people will find it not as pleasurable let say after a year of the regular cake consumption. What happens to the brains of people when phycological response to some stimulus dulls with time? Can we do something to the brain, so it will always excite with the same strength to some particular stimulus? I think the same thing can be related not necessarily to the sensory perceptions, but als…

Hi all, When eye retina send impulse to brain, brain then use data from impulse to create impression of color. What is this final process called? What should I Google for? I can not wrap my head around the transformation of data to world impression....

I'm thinking about what the implications of sleepwalking are for free will and consciousness, so I'm wondering what are the most complicated, most cognitively demanding acts that people have done while sleepwalking. Furthermore, is there some way that we know that a person is not conscious while sleep walking? Something that closes off the possibility that perhaps a person is conscious while doing this, just doesn't remember it afterwards.

What changes internally in a growth - like an intestinal adenoma (pre-cancer) for example - that makes it malignant? Or why does increasing size mean it increases the chances of it becoming metastatic? Does the already disfunctioning cells increase in disorder in their DNA with each new replication or new generation?
