Green tea is an example of skin remedy that is good for the skin. It has polyphenols antioxidant that gives green tea an anti acne fighting power. Polyphenols has natural compound that is antioxidant, anti-inflammatory and anti-carcinogenic in skin which helps modulate inflammatory responses of the skin, chemical tumor causing promoters, ultra violet skin induced inflammations and oxidative stress. It also means that it protects the skin from sun causing skin damage, signs of aging, and it could treat inflammatory skin conditions. Baking Soda Skin Exfoliant: This is one of the most effective methods of getting rid of acne there is. All it involves is a damp …

I was just reading a pretty good science fiction novel called 'Beneath', by Jeremy Robinson the other day that involves a manned mission to Europa. One of the things about it that interested me about it was that the astronauts were put into sedation for the duration of the flight and kept alive via intravenous nutrients, as well as microshocks to prevent their muscles from atrophying. I was just wondering; would anything like that be possible using current technology? I mean I've heard of people being sedated for long periods of time, and coma-patients are usually kept alive by intravenous nutrients (I assume), so would something like this be possible now or in the n…

In your own mind map with the center pivotal word being "neuroscience", what would your first nodes be?

As I previously posted, I am going for a leg lengthening operation in about 3 months and am currently researching the topic....vigorously (!) It would be very much appreciated if anyone knows of a good leg lengthening book. And yes...please don't google "leg lengthening book" 'cause that is not the point (I could do that myself ;-)...) What I am looking for is for a LL book somebody actually read AND thought it was good... Lord knows there is plenty of @#$%^ out there... Very much appreciated!

Hello all. What foods make human blood pH to raise its alcalinity? What foods make human blood pH to decrease into acidity ? What human body organ fights pH changes to keep the blood at its optimal pH ?

Hello, Please have a look at the diagram below. I made this. I'm trying to illustrate the pathways visual information takes in the case of fear stimuli. For example, seeing sharp fangs and piercing eyes. I'm trying to demonstrate how the fear reaction occurs independently of the actual seeing of the stimulus. I want to know if my diagram is correct. I'm trying to dispell the natural assumption that we get scared at sights like sharp fangs and piercing eyes because they look scary. Since the fear occurs (at the amygdala) prior to seeing the stimulus (in the visual cortex), it can't be the sight of the stimulus that scares us - it can only be a correlate. I …

Dear All, I am currently a PhD student in the Radiation Oncology Department at UCLA. I have thought for a long time that it will be really beneficial for my lab if we were sharing the interesting articles that we find on the web with each other . I tried to implement a system in my department and I went to Connotea/ Mendeley / Citeulike, etc etc. However, all of these networks are reference management systems and none of them offer the experience (and the rewards in that sense) that social sites like Twitter, Facebook, Digg etc do when you share something. These vertical scientific social networks are more about managing references than what they are about shari…

I was just being curious, and thought this would be the best place to post it? So what makes us tickle in a specific area [you could pick the area]. Is it something to do with the Interstitial Fluid or, just some electric impulse. I know its a really tough question, but lets explore on it

Each taste, from sweet to salty, is sensed by a unique set of neurons in the brains of mice, new research reveals. The findings demonstrate that neurons that respond to specific tastes are arranged discretely in what the scientists call a "gustotopic map." This is the first map that shows how taste is represented in the mammalian brain. There's no mistaking the sweetness of a ripe peach for the saltiness of a potato chip -- in part due to highly specialized, selectively-tuned cells in the tongue that detect each unique taste. Now, Howard Hughes Medical Institute and NIH scientists have added to our understanding of how we perceive taste, showing that four of our basic…

Acne rosacea, often called adult acne, is a facial condition that is different from teenage pimple acne. Rosacea causes the face to get permanently red in the center portion of the face and nose. It starts with on a off blushing red, and then as it gets worse the face stays red. It itches and can cause skin flaking. I read that it is a little understood condition. Well, I think I understand it, what causes it and what can cure it. I had Rosacea and was forced to devise my own cure because the condition was supposed to be incurable. I will just tell you. If you don't have enough regular bowel movements over a long period of time [months] the blushing red face of rosacea …

In an effort to understand what happens in the brain when a person reads or considers such abstract ideas as love or justice, Princeton researchers have for the first time matched images of brain activity with categories of words related to the concepts a person is thinking about. The results could lead to a better understanding of how people consider meaning and context when reading or thinking. The researchers report in the journal Frontiers in Human Neuroscience that they used functional magnetic resonance imaging (fMRI) to identify areas of the brain activated when study participants thought about physical objects such as a carrot, a horse or a house. The research…

Hey guys, I was (actually, I still am) wondering why neuronal activation that is induced by administration of leptin is commonly detected by pSTAT3 immunoreactivity and not by e.g. cFos. Leptin binding to its receptor activates STAT3, I know. That means that pSTAT3 IR is a marker for the activation of the leptin receptor. Why not looking directly on the actual activation of the neuron, by monitoring the translation of the immediate early gene cFos? CFos is also a commonly used marker but, as opposed to pSTAT, it's a more direct evidence for the activation of the neuron, isn't it? What do I miss here? Any help is greatly appreciated. stupid.me

I was reading a neuroanatomy book lately. I noted that every time a description of a nerve is made, the author has said the "fibers to the structure". There has been no distinction of whether the fibers are sensory or motor. Both are described as "fibers to the structure". My basic knowledge of the nervous system tells me that motor nerves start from the cerebral cortex (mostly the pre-central gyrus) through the spinal cord or cranial nerve nuclei reaches the structure. Sensory neurons, in contrast, starts at the sensory organ to the spinal cord or cranial nerve nuclei to the relaying stations in the brain and finally to the cerebral cortex (mostly the post-central g…

Being introduced to the brain science, one typically learns about line detector neurons in area V1. But I don't recall learning about curve detector neurons. Are there any?

hi all.. I just remember the days I had to pass my anatomy exam for the second time, and badly at the end I failed.. I always hated anatomy, think lots of you share my feelings. one day one of my good friends (my previous Boss actully) send me this link and it change everything just want to share it with all of you http://www.how-to-st...physiology.com/ best regards Rana plz share your thoughts with me

I was just asking about muscles growth. Is this get done through enlargement of fibres or formation of new ones? If both, then dependent upon what?

While reading a topic about web color contrast I found this interesting information: As an art teacher, I have experienced first-hand one of the elements he [itten] mentions, the fact that people tend to prefer their own physical coloration, that is blue-eyed blond(e)s like blue and yellow specifically, and light, bright, pastel colours in general, while olive-skinned, dark-eyed people tend to prefer browns, blacks, and other deeper, more saturated colours. I was covering an art class once where a blonde student was being pressured by her brunette teacher into darkening and deepening the colours of her painting. I explained her teacher's natural colour bias, …

So I was wondering how MSCs get recruited into the growth plate. Like this? MSC > Condensation > Commitment > chondroblast > chondrocyte or MSC > invasion via sox9 > differentiation > chondrocytes

Gardeners know that some trees require regular pruning: some of their branches have to be cut so that others can grow stronger. The same is true of the developing brain: cells called microglia prune the connections between neurons, shaping how the brain is wired, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, discovered. Published online in Science, the findings could one day help understand neurodevelopmental disorders like autism. "We're very excited, because our data shows microglia are critical to get the connectivity right in the brain," says Cornelius Gross, who led the work: "they 'eat up' synapses to make space for the m…

If the neurons in your brain could somehow be activated w/o neurotransmitters would you be conscious?

Hello fellow brain enthusiasts, We are a small group of filmmakers working to produce and shoot a film fueled by neuroscience. It's a story of friendship, hope, music and the mind, and the inherent connection between people. All people. It's a heady concept, a complex story, a simple message, and has one hell of a team backing it up (us). And, profits from the film will be donated to various organizations dedicated to studying visual perception (like the experiments in our film) and Creutzfeldt-Jakob disease. Which we're very proud of and excited for. But we need help. Before going into that, check out our website, or our little explanatory video: …

Greetings, I have a herniated disc that makes a small bulge into the nerve in my lower back. I've read that the bulge can be removed by discectomy, but that the herniation doesn't heal. What prevents the disc from healing? I'm not medically trained, so pardon my ignorance, but shouldn't the herniation close eventually and scar? Is the lack of healing due to the material the disc is made of? If so, what is that material/tissue? If it's not able to do this, couldn't someone make an adhesive to put in the tear or tape that can be placed over the tear to keep it closed? Sorry if this sounds inane, but this thing is driving me crazy and so it's leading me to all sorts of sche…

Hi all, Check this link for books on Neurology and Neuroscience; I thought its a useful information to share Cheers Loka

The human body has some internal organs which are single. But others, we've got two of. For example, we've got two kidneys, and two lungs - but only a single liver. Yet the liver is an essential organ. If it fails, we die. Shouldn't it have a back-up, like a kidney has - if a kidney fails on one side, there's another on the other side, to take over. A person can survive with one kidney. And it's the same in the case of the lungs. A person can have a lung surgically removed, and still get by on the other "back-up" one. This "back-up" principle seems very sensible and prudent, from a survival viewpoint. And survival is what Natural Selection is supposed to …
