5 Ways Your Brain Is Messing With Your Head We accept on a regular basis the premise that our minds are being screwed with. Advertisers, politicians, magicians; we accept that they know the tricks to pull the wool over our eyes. But as it turns out, the ways in which your head is being truly and royally messed with the most, are coming from inside. Please be advised that your brain does not want you reading the following list, and may kill you to protect its secrets. #5. What is it? It's your inability to notice changes that happen right in front of you, even if they're hugely obvious... as long as you don't see the actual change take place. Um, What? Consider Alfonso Ribeiro. Now, if suddenly that image of Carlton blinked and changed to a different image, you'd notice it. In fact, if the entire text of this article--and the whole color and layout of this website--changed while you were gone, you probably wouldn't notice. A scientist named George McConkie started working on this in the 70s. Why Does the Brain Lie About it? #4. #3.
Does the head remain briefly conscious after decapitation (revisited)? A Straight Dope Classic from Cecil's Storehouse of Human Knowledge June 12, 1998 Dear Cecil: In the answer about the guillotine in your online archive, you say that "the fatal blow induces immediate unconsciousness." In actuality, the human head does remain conscious fifteen to twenty seconds after decapitation. — Joel Brusk, via AOL Dear Joel: Let's see. A lot of people disputed my claim that victims of the guillotine blacked out immediately. Not likely. But let's return to the original question, appalling though it may be: Is a severed head aware of its fate? It doesn't get any better. Is it possible? Then I received a note from a U.S. My friend's head came to rest face up, and (from my angle) upside-down. I've spoken with the author and am satisfied the event occurred as described. — Cecil Adams
Your Diet Affects Your Grandchildren's DNA, Scientists Say | Epigenetics You are what you eat, the saying goes. And, according to two new genetic studies, you are what your mother, father, grandparents and great-grandparents ate, too. Diet, be it poor or healthy, can so alter the nature of one's DNA that those changes can be passed on to the progeny. While this much has been speculated for years, researchers in two independent studies have found ways in which this likely is happening. The findings, which involve epigenetics, may help explain the increased genetic risk that children face compared to their parents for diseases such as obesity and diabetes. The punch line is that your poor dietary habits may be dooming your progeny, despite how healthy they will try to eat. [10 Worst Hereditary Conditions] Epigenetics Epigenetics refers to changes in gene expression from outside forces. Recent studies have shown how nutrition dramatically alters the health and appearance of otherwise identical mice. Of mice and humans Attack on the DNA
The 6 Most Mind-Blowing Animal Senses You probably already know that when it comes to everything but intellectual pursuits and wearing cardigans in a knot over one's shoulders, animals have humans beat. All of your senses together can't match what a dog can pick up with its nose, for instance. But every now and then, an animal's sensory superiority goes above and beyond the usual and takes a turn for the bizarre and/or terrifying. #6. Vampire Bats Have a Map of Your Veins Wikipedia Vampire bats are the only mammals that subsist entirely on blood -- otherwise, we'd just call them "bats." Livescience.comBats only appear on film as 1980s school photos. That nose that God forgot actually does more than just invite business cards of bat plastic surgeons -- it can sense the heat of your blood flowing through your veins. Its nose-lip combo contains infrared heat cells that can sense the warmth of the blood at a distance. WikipediaIt's the fact that they refuse to eat or drink unless it's served to them in a sterling silver bowl. #5.
5 Mind-Blowing Ways Your Senses Lie to You Every Day We are so completely dependent on our five senses every moment of the day that we totally forget how full of shit they can be. Your reality is cobbled together from a bunch of different parts of your brain working in conjunction, and often it's like a bickering conference room full of uncooperative co-workers. In fact, we're pretty sure the thing your brain does best is convince you that it works. But it doesn't take much to spot the bizarre little flaws in your gray matter. For example ... #5.

In the clip, you see (and hear) a guy saying "bah bah bah" over and over. BBCYour brain also gave the "fah" version a tan, for unknown reasons. This illusion is called the McGurk effect, and the creepiest part is that, even knowing know full well what's going on, you can't get your ears to hear the correct sound. #4.

5 Things You Can Do Right Now to Become Instantly Smarter There might not be a worse feeling than when you have some kind of huge project due and the creative part of your brain just slowly grinds to a halt. Some people have little rituals they go through to try to jump-start their muse, from "take a relaxing walk" to "steal someone else's idea and then secretly murder them." But why not look to science to figure out what actually works? Well, we don't guarantee that any of the below will work for you -- all we can say is that smarter people than us have gotten them to work under scientifically controlled conditions. They also happen to cost absolutely nothing, so if you need to force you brain to start thinking outside the box, try to ... #5.

Cosmic Rays: 100 Years Of Mystery : 13.7: Cosmos And Culture hide captionAn artist's impression of the quasar 3C 279, about five billion light years away. This quasar contains a black hole with a mass about one billion times that of the sun. M. Kornmesser/ESO An artist's impression of the quasar 3C 279, about five billion light years away. This August, physicists are celebrating the 100th anniversary of the discovery of cosmic rays, showers of particles raining down on us from outer space. Apart from their mysterious acceleration mechanism, cosmic rays also have a very practical impact on our world, producing about 13 percent of the natural background radiation in our environment. And then there is the issue of space travel: radiation exposure remains a serious barrier to longer manned expeditions. In August 1912, the Austrian physicist Victor Hess flew in a balloon to altitudes of 5.3 km, measuring the flux of particles in the sky. In the following decades, cosmic rays became a great tool for exploring the fundamental building blocks of matter.
3D map of human brain is the most detailed ever - health - 20 June 2013 The folds, creases and intricate internal structures that make up the human brain are being revealed in unprecedented detail. A new three-dimensional map called BigBrain is the most detailed ever constructed, and should lead to a more accurate picture of how the brain's different regions function and interact. Until now, the precise placement of the neurons that make up our brain circuitry has been difficult to map, largely because the human brain's surface is covered with folds and creases. Slicing a brain exposes only two dimensions, so it is often unclear where and how the cells within these folds are organised in three-dimensional space. To make the new map, Katrin Amunts of the Jülich Research Centre in Germany and her colleagues embedded a 65-year old woman's brain in wax, sliced it into more than 7400 sections each 20 micrometres thick – one-fifth of the width of a human hair – and made digital images of the slices, also at a resolution of 20 micrometres.
