Anatomy, Physiology and Neuroscience

My teacher told me that he read some news about some women having 4 types of color "sensors". I hadn't bothered to ask him to define this phenomenon more specifically. So basically, the average person has 3 color sensors, which are the three primary colors of additive color theory. So what is this 4th color sensor? I couldn't find the news on this, so hopefully someone here knows the source of this news.

For the first time on an example of mammals is experimentally found,criterion of health according to which operates {work}: natural selection and areproduction of viable organisms, and also an interdiction and realization ofinfinite variants of pathology. The establishedcriterion allows carrying out the control of parental levels of viability before the beginning of conception of descendants,and opens a new era in prevention of illnesses at people and animals duringtheir reproduction. As criterionof health or viability of organisms the found opposition of levels, i.e.parameters of speed of a nitrogenous (albuminous) metabolism is accepted. It isshown, that low …

Sacroplasm Fluid Hey guys, thank you so much for your time. I am not a science student but I am studying about the human body out of personal interest. I have been looking for articles and videos that explain the nature and function of the Sarcoplasm fluid but sadly I have not found any that explained what I wanted to know. I am sure you are aware of the panic that is being spread around in the fitness world about how rep counts higher than five induces sacroplasmic hypertrophy? Here is just what I am confused with: What is the function of the sarcoplasm fluid and what are its content? I know that it is just like the cytoplasm fluid of ot…

What happens while viewing a Stereogram To the Eye, To the Brain, To the Mind (OPTHALMO - NEURO - PSYCHO LOGICALLY Do the two Eyes cross while viewing a Stereogram. What is special, specific about the distance between the two Eyes when the two Eyes click and the two images coincide to form a third 3D image. Is it true EEG shows no change while Stereogram viewing, But FMRI shows blood flowing to some part of the Brain (*Which Part, To what effect). Will prolonged viewing affect the Eye, Brain, Mind. Can Stereogram viewing be turned into a good creative exercise. Are the wonderment, The depth, The concentration, Absorption real and good. Can this be used as a therapy for c…

Hi ya this is Howl here, I think I've found away for humans to get wings with but requires grafting but with future help it may become perfected. First off I'd like to state that my idea is inccrediably painful but if your as dedicated as I am i think you can endure it. Secondly it may sound a little out their but aren't all scientific descoveries? Okay, I was thinking that we in a sense collect the requied body parts such as a heart from a horse since its so big an has the ability to pump large amounts of blood through it, there's also a drug they use on cows to make their upper bodys stronger which would be need to help the upper bodys of humans substain the weight…

Has science made any progress in understanding severe anxiety disorders as to what exactly is going on in the mind and body of those who have periodic episodes of anxiety issues? I have had anxiety issues since I was little which I self medicated by consuming chocolate or alot of sugar. I didn 't understand at that time what was wrong with me or if what I was feeling was out of the norm compared to everybody else. Later in my 30's I experienced the worst anxiety attacks which occurred about twice a year. These attacks can last up to a week and my symptoms begin with: 1. Starts in my stomach feeling anxious 2. I get a metal taste in my mouth 3. Tingling se…

While the neurologically relevant pathways of phenylalanine are certainly varied, I'm wondering if we can get together what we know about them in a diaphanous form. Such may make it available to both common intellectuals and harried experts: the latter don't always put together info as well as it could be presented to them.

Does omega-6 inflammation induce vascular permeability and what is the gravity of such?

how does the decision to get up out of bed lead us to actually getting up out of bed?

Hi, I want to know more about how the brain can be improved as in better memory, quicker/more complex thoughts etc. But my searches only give gimmick sites promising to do it for you in exchange for your money. I'm interested in the actual science behind it, I'm assuming it hasn't got to the point where you can seriously improve your brain yet but neuroscience is too general and none of the more specific terms I have come across really describe what I mean. Is there a name for it? Regardless of that I would like to learn about it, real details, despite how complicated it might be so a point in the right direction would be appreciated. I have no real knowledge …

Relationship between insulin degrading enzyme and Alzheimer's: http://www.sciencema...5500/2302.short Lowered glucose metabolism in Alzheimer's: http://www.pnas.org/...7/11/6037.short I'm wondering whether Alzheimer's is associated with insulin deficiency, and if so, why its treatments don't include insulin injection.

These are a few of the experiences that I have had over the years. I had posted this in the Lounge but perhaps that was not the right place for this. I apologise for the repetition. I am looking for some help and guidance to formulate a theory behind these experiences and to evolve a technique to make these exercises repeatable. If a theory and technique are evolved, this could give legitimacy to these exercises which could benefit the society at large as a de-stress therapy. There is no commercial motive behind this. Experience 1 - BEHEADED I tensed ,flinched inside my head close to the cervical spine. I felt a DISCONNECT between my head and neck. My …

I just picked up a pamphlet promoting a spray that claims to bring muscle-pain relief. I believe DSMO may penetrate the skin and possibly even acetone, but even that is questionable to me. Any good info?

I was asked this question and could not answer it, to any real extent. Why do emotions lead to the crying response or to tears in the eyes? Are these responses the same in babies and adults? Which part of the brain is responsible? Partial answers and reference to papers welcomed.

A question that has been on my mind is what is the first type of tissue that the zygote forms after conception? As far as I know, and please correct me if I'm wrong, the sperm and the egg fuse to form the (or at least the origin of) embryonics stem cells. These stem cells are then capable of differentiating into any cell type in the body. I'm guessing that it doesn't form one organ, then moves on to the next one, and so on, but rather develops all or most of the organs at a gradual rate simultaneously. But I'm just wondering if there is a starting point, e.g. the brain or the heart, on which the other organs are developed around. Does the body of the mother have any role …

Why do you sometimes shape your mouth so that it's actually a little harder to breathe out? You do this sometimes during (endurance) sports, or when you do a deep sigh. Here is an example (picture). Why do we do that? Is it to increase the pressure in the lungs, and therefore increase the oxygen intake? If so, does anyone know what the pressures in the lungs can be (the highest possible and the lowest possible during regular respiration)? If that's not it, then what is the reason?

Regarding the premotor area of the cerebral cortex, does it have an effect in the respiratory rates during exercise? If so, at which stage is that (i.e; immediate, secondary, or later stages)? Thanks.

If the so called ' Thought ' is part of human physiology , does it not render the phrase ' I think .. ' as senseless and mere fabrication ?

I'am interested in human brain growth and have some doubts. Suppose there are two identical persons. The first person in teenage years (14-20) diligently studied maths and physics, and the other person didn't. 1. What are the differences in their brains structure? 2. If second person would start learn maths and physics in adult years (>23), is she able to fill the gap and develop her brain to the same state? 3. Does adult human brain creates new synapses while learning, escpecially mathematics, physics and logic? I thought that their level falls from 4th year of age. 4. (If answer at question 3 is "yes") In adult ages the myelining process is finished, so won't…

From Wikipedia Was just reading about this in relation to consciousness. Some reasearchers have suggested that the gamma waves observed in EEGs may related to consciousness. And that the reduction of gamma waves by expert Tibetan mediators can induce a state of 'selflessness' where consciousness is modified or eliminated, at least as we normally experience it. I must get a copy of ' The Emperor's New Mind ' and see how ideas of quantum consciousness fit into this.

Just like a video camera does. I was told once by a psychiatric nurse who worked at a hospital that everything is recorded on your brain, not just sight either, that everything you've ever experienced is there, from all 5 of your senses. But the reason we can't recall it all is because most of it resided in our subconscious. You can remember specific facts when you specifically look for them, like phone numbers, addresses, passwords, directions, how to drive a car, etc. That your conscious is somewhat like a computer's RAM which stores something the computer is currently working, while the hard drive has information on all the data on the computer. If you view this, scien…

I have noticed that if single black hair is pulled out from skin by pincers, it appears to be white near the thick root. I.e. the black color is appearing far frome the hair root. Does this mean that coloring pigment is generated far from the place, where hair material itself is generated? Or this means that pigment undergoes some sort of maturation during the grow? Thanks.

I am going for a leg lengthening operation, 7 cms in 3 months!! I would love to hear if there is anybody in this forum that has any experience with this type of surgery. I got a chance to visit an LL (leg lengthening) clinic and met a whole bunch of patients undergoing the treatment...I was amazed of how much this has changed through the years.... I was researching it a couple of years ago and could only find these horrible external fixators with pins and rods going through your skin and bones (horrible!!!)... Now everything is internal, they implant a nail in the bone and that's it! You distract at 1mm a day until you reach whatever height you are going for an…

The original question asked:Which of the following is (are) often absent in thick skin but typically present in thin skin? Arrector pili muscles Meissner’s corpuscles Stratum basale Stratum corneum--I know it is not this one for sure I think it is the Meissner's corpuscles since they have to do with pain/touch, but am unsure. Can someone help me confirm?

The neurological basis for decision making has always interested me, for the fundamental reason that how can you actively make any decision if it is all up to the chemistry in your brain, surely at some level it the conclusion you end up with is just fate based on the "chemical balance" of your brain at the time of the decision. This has been shown to be true in many cases; mood and environment effect peoples decisions, soft chairs have been shown to increase peoples leniency in negotiations, thoughts of disgust and therefore dislike have been superimposed by the brain over whole scenarios even if the subject knew of the artificial cause and it was nothing in the sce…
