Hello, I am not sure if this is the correct forum for these question but I have a feeling. At least this seems to be a place with a lot of smart people, which always is a great start. I want to start off by saying that I have been a stutterer for the most of my life (I am 18) and now it is significantly bad. I noticed that the whole last year was totally stutter-free but this year, it has turned bad once again. The stuttering does not differ when talking to strangers, family, doing presentations at Uni or talking in general - I stutter equally in each situation. However, I do not stutter at all when I am alone or talking to my pets. In fact, I have a youtube channel …

When do you think will repair of a damaged retina be possible and with what technology? Asking this as a ROP (retinopathy of prematurity) survivor... one with very poor eyesight. I can barely see a human from 100 meters away (and they appear really really tiny) I can't properly recognize facial features from 10m away (I can recognize people though) and I can't read normal books except from a few cm's away. Most of my field of view is in my right eye, my left eye is even weaker and I can't read anything with it (it is not blurred but I still can't see). No medical intervention for my condition is currently available.

Hey all, I'm aware that this is not a drug forum and that drug related questions get frowned upon at times, but this is a question to which I want an honest answer from experts in the field, based upon empirical evidence, previous research and existing literature and not some pothead answer who's knowledge is based on street myths. I got sick a month ago, and two weeks later was diagnosed with infectious mononucleosis. I'm not sure if it's done the same way here as it is in other countries, but with me they tested for the amount of white blood cells in my body, which was found to be thrice the normal amount (I remember the number being 29000, I believe the unit wa…

I spend alot of my time sitting in college and the bus etc everyday since starting college and am losing my six pack. My brother recommended using an exercise ball as a chair to work my abdominal muscles at home. What are the advantages and disadvantages of using an exercise ball as a chair over say getting a standing desk??

Is pain a warning to ourselves that we should not overstress certain parts ? -Say pain in a foot- is a warning to need to rest, lay down, be gentler in use of such foot, or worse conditions will develop ? Or a dislodged articulation; or a cactus spine stuck in the flesh... or... Physicians prescribe pain medicine so the -foot- pain is not felt and keeps you walking/running/abusing the ailment... but is ignoring the nature sign of 'need to rest' and worse conditions can easily develop ? Can pain medication promote worsening by masking/ignoring a symptom ? Does it make sense ? When I asked that to a doctor pushing me for pain killers, his jaw dropped and ignore…

Does anyone have links to studies done about the difference in body functions during analgesia? I have looked on multiple search engines and nothing comes up.

Why you don't want to sleep when you exercise in the evening? When you exercise, body temperature rises, so the melatonin decreases and you don't want to sleep, yeah? I think that rise in body temperature wakes you up, but, on the other hand, rise in the body temperature denature proteins.. I know that Dopamine can directly inhibit production and release of a molecule, melatonin, that induces drowsiness and prepares the body for sleep, but does endorphin? Does exercise increase dopamine or endorphin? The general question would be: What does make you want to sleep? And what does make you not want to sleep? Exactly. Thanks.

My 8-year old grandson plays the violin. He usually tunes his violin before a lesson, using his teacher's electrical device which measures pitch exactly (you specify, say, middle A and play the note, and the machine shows green if spot on). Yesterday he tuned his violin at home, this time using his mother's identical machine which she uses for singing practice. He then claimed the machine was wrong, it wasn't the same note. This was dismissed as nonsense, but she checked later and discovered that her machine was set to A=440 Hz (Concert pitch in the UK and USA), whereas the teacher's machine was set to A=443 Hz which is standard in Germany (where he and his teacher live…

Is Visual Spatial IQ test to test how well you can remember shapes? A person that does well on Visual Spatial IQ test will do well drawings, art and architecture drawings. A person with low Visual Spatial IQ test will do really bad with drawings, art and architecture drawings. Why are some people really bad at Visual Spatial IQ test? And other people can remember lots of detail and really good at shapes in their head? Some people are really good at doing drawings and art work. Can Visual Spatial IQ test be improved by teaching your brain to remember detail?

"Those treated with both irradiation and the cannabinoids saw the most beneficial results and a drastic reduction in size. In some cases, the tumours effectively disappeared in the animals. This augurs well for further research in humans in the future. At the moment this is a mostly fatal disease. "The benefits of the cannabis plant elements were known before but the drastic reduction of brain cancers if used with irradiation is something new and may well prove promising for patients who are in gravely serious situations with such cancers in the future." http://www.sciencedaily.com/releases/2014/11/141114085629.htm

Question: what are if any the differences in brain activity between adults and children when using imagination.

I'm an organ donor and have been for many years now. As have all my friends and family. Registering as an organ donor, as far as I can tell, seems to be the done thing now - especially as policy change across the world gradually sees more national 'opt-out' organ donation models. I assumed shrinking transplant waiting lists. But then I came across this article: http://careers.imhgroup.net/link-self-driving-cars-organ-donation/ While there are apparently more donors, according to this article there may well be fewer actual donations thanks to medical advancements. I guess my question is WHAT IS THE ANSWER? WHAT WILL BECOME OF US? I'm just c…

Say you're a pediatrician. You come across a patient's parents who express concern for vaccine-induced autism and it depends upon you to assuage their fears. An example argument I've come across is that cases of mitochondrial dysfunction are potential hazards when a post-vaccine fever presents itself, leading to poor metabolism in the brain, resulting in permanent brain damage and autism-like symptoms. If you attempt to explain the counter-science (not to mention the essentially nonexistent correlation), it doesn't matter. How do you approach parents who are 100% obstinate to scientific research? How do you approach ANYBODY who is unwilling to read any further than a c…

I've heard and read from various sources that vaping was found to contain the chemical diacetyl which gives the vaping liquid its delicious buttery flavor. I've heard that this is linked to a condition known as "popcorn lung". This may be an old question that is either debunked or confirmed, but I just wanted to know what the smart folks here thought about it. Does using vaporizers cause a real threat to human health/life? Thanks.

Hi all Does anyone know if klonopin and motrin use the same pathway? I took motrin after a wisdom tooth extraction. I've taken a small dose of klonopin for sleep many years. I think my klonopin was decreased by motrin

Hi! my supervisor wants me to use exosomes in our model and I am trying to follow th methodof Nat. Protocols El-Andaloussi et al 2012 and Alvarez-Erviti Nat Biotech 2011 but I am not getting any silencing in the brain and I have just seen these comments in you tube and in this blog talking about fraud and saying that this papers should be retracted! who should I trust? does anybody know other protocol for brain delivery of siRNAs using exosomes? I am quite desperate! any advice would be greatly appreciated! http://metamodern.com/2011/03/22/across-the-blood-brain-barrier-with-exosomes/ Cheers

You always hear about the health benefits of exercise, but it seems to me that when people say exercise they usually mean something like running, cycling or swimming. I'm wondering is there any evidence for any health benefits to weightlifting? And I don't mean muscle gain or fat loss, I mean are there any benefits beyond that that you don't get through running?

I have been told that gamma beams cannot work with ball lenses, but X-rays, and other electromagnetic radiation, I am unsure about. how much can gamma knife beams be collimated without using ball lenses. What would be the smallest cubic area in the brain you could ionize, without gamma beams passing through a ball lens. Can you tell me the effects for X-Rays, and other electromagnetic radiation, if they can pass through a ball lens or not. If you can ionize neurons at micron scales you can stop the spread of Parkinson's disease throughout the brain. It would be tricky, and complex, but not impossible. You could probably erase memories specifically in an animal also,…

I believe one of the terminating ILLNESS for Human Beings particularly in their OLD AGE is the very Popular COLD and its Manifestations ! I understand COLD is a Virus ! Don't we require to channelize all our energy to FIGHT THIS VIRUS with concentrated Research and Scientific Efforts ! Something like a VACCINE or CURE to Remove this Virus from Earth or at least from Human Beings ! Just Brainstorming here !

If you start feeling that your are on the edge doing normal activities and that small inconsistencies in life set you off, you may have been infected with a form of herpes/shingles. This may have been spread to you unintentionally or intentionally through food or being around people who do not cough into something. Shingles can mimic the symptoms of psychosis which could make it very difficult to treat.

What is the motor threshold when using transcranial magnetic stimulation, in Tesla?

Why cant RBCs diffuse across other cell membrane just like other cells ? This question has been bugging me for days and I've scratched my head way too much🙈😹 . I read about it and about the interstitial fluid in the tissues could be the reason why they don't diffuse in tissue cell membrane.. but I'm not just satisfied so can anyone please help,?

I'm interested in the author's intent in the conclusion of this paper in the last bolded line. Are they saying 'yes' optimism is good and 'yes' it is not good, or 'yes' it is good for immunity?

For those who know, we know that our subconscious get affected oftenly by the outer environment, also if our consciousness is moulded by what our subconscious mind feeds upon, then it could simply mean that we are all prisoner of influences. What do you say?
