Mirror neuron A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another.[1][2][3] Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting. Such neurons have been directly observed in primate species.[4] Birds have been shown to have imitative resonance behaviors and neurological evidence suggests the presence of some form of mirroring system.[4][5] In humans, brain activity consistent with that of mirror neurons has been found in the premotor cortex, the supplementary motor area, the primary somatosensory cortex and the inferior parietal cortex.[6] The function of the mirror system is a subject of much speculation. Discovery[edit] Further experiments confirmed that about 10% of neurons in the monkey inferior frontal and inferior parietal cortex have "mirror" properties and give similar responses to performed hand actions and observed actions.

How to discover your life purpose in about 20 minutes How do you discover your real purpose in life? I’m not talking about your job, your daily responsibilities, or even your long-term goals. I mean the real reason why you’re here at all — the very reason you exist. Perhaps you’re a rather nihilistic person who doesn’t believe you have a purpose and that life has no meaning. Here’s a story about Bruce Lee which sets the stage for this little exercise. If you want to discover your true purpose in life, you must first empty your mind of all the false purposes you’ve been taught (including the idea that you may have no purpose at all). So how to discover your purpose in life? Here’s what to do: Take out a blank sheet of paper or open up a word processor where you can type (I prefer the latter because it’s faster).Write at the top, “What is my true purpose in life?” That’s it. For those who are very entrenched in low-awareness living, it will take a lot longer to get all the false answers out, possibly more than an hour. Give it a shot!
Regeneración neuronal: está comprobada Toda la vida se nos dijo que las neuronas no podían regenerarse. Uno nacía con una cierta cantidad y a lo largo del tiempo las iba perdiendo de a poco. Si por alguna razón las neuronas de cierta área del cerebro se morían, se producía un daño irreparable. Este concepto ha cambiado en los últimos años. Artículo 1:LAS NEURONAS MUERTAS INDUCEN EL NACIMIENTO DE NUEVAS NEURONAS ( Publicado en Revista Creces, Septiembre 2000 ) Hasta hace muy pocos años se afirmaba que el cerebro nacía con la dotación definitiva de células y que éstas sólo podían morir pero nunca renovarse. En la revista "Nature" de Junio 22 de 2000, el neurocientista Sanjay Magavi y sus colaboradores del Children Hospital de la Universidad de Harvard, reportaron que induciendo la autodestrucción de neuronas ubicadas en la neocorteza de ratas adultas, se gatillaba un proceso de reemplazo de neuronas a partir de células troncales (stem cells).

The New Map Of The Brain Trying to map the brain has always been cartography for fools. Most of the other parts of the body reveal their workings with little more than a glance. The heart is self-evidently a pump; the lungs are clearly bellows. The struggle of the mind to fathom the brain it inhabits is the most circular kind of search--the cognitive equivalent of M.C. Modern scientists have done a far better job of things, dividing the brain into multiple, discrete regions with satisfyingly technical names--hypothalamus, caudate nucleus, neocortex--and mapping particular functions to particular sites. Slowly, that is changing. Specialized neurons are being found that allow us to mirror the behavior of people around us, helping us learn such primal skills as walking and eating as well as how to become social, ethical beings. Human beings have always been brash enough to ask such questions but lacked the necessary gifts to answer them.
How to Use English Punctuation Correctly - WikiHow Steps Part 1 Using Proper Capitalization 1Always start a sentence with a capital letter. Unless you're an avant-garde poet or you're starting a sentence with a brand name like "wikiHow" or "iPod," you will need to capitalize the first letter of every sentence. Here is an example of proper capitalization at the beginning of a sentence: She invited her friend over after school. 2Use capital letters to start proper nouns and titles. Part 2 Using End-of-Sentence Punctuation Marks 1Use a period (full stop) to end declarative sentences and statements. Part 3 Using Commas 1Use a comma to indicate a break or pause within a sentence. Part 4 Using Colons and Semicolons 1Use a semicolon to separate two related but independent clauses. Part 5 Using Hyphens and Dashes 1Use a hyphen when adding a prefix to some words. Part 6 Using Apostrophes 1Use the apostrophe together with the letter s to indicate possession. Part 7 Using Slashes 1Use the slash to separate and from or, when appropriate.

Ads Implant False Memories | Wired Science My episodic memory stinks. All my birthday parties are a blur of cake and presents. I’m notorious within my family for confusing the events of my own childhood with those of my siblings. And yet, I have this one cinematic memory from high-school. It’s an admittedly odd detail for an otherwise logo free scene, as if Coke had paid for product placement in my brain. So where did this sentimental scene starring soda come from? A new study, published in The Journal of Consumer Research, helps explain both the success of this marketing strategy and my flawed nostalgia for Coke. The experiment went like this: 100 undergraduates were introduced to a new popcorn product called “Orville Redenbacher’s Gourmet Fresh Microwave Popcorn.” One week later, all the subjects were quizzed about their memory of the product. The scientists refer to this as the “false experience effect,” since the ads are slyly weaving fictional experiences into our very real lives. Image: irene/Flickr.
Home Page - The Chartered Institute of Purchasing and Supply Descubren nuevo tipo de neurona -Muy Interesante México ciencia/ 02/10/14 Investigadores de la Universidad de Heidelberg y la Universidad de Bonnn, ambas en Alemania, han descubierto una nueva forma de neurona, que los mantiene intrigados acerca de cuál es su función. A pesar de que las neuronas vienen en diferentes formas y tamaños, su estructura básica generalmente consiste en el cuerpo de una célula, de la que sobresalen apéndices alargados llamados dendritas y axones. Las dendritas son estructuras que parecen ramas de árbol, que reciben señales de otras células nerviosas y las depositan en el cuerpo de l célula. Las neuronas procesan la señal y la dirigen a la siguiente célula por medio de una prolongación larga y delgada llamada axón. El descubrimiento presenta un proceso distinto, desconocido hasta ahora. Las nuevas células fueron descubiertas en el cerebro de un ratón, en el hipocampo, una estructura cerebral profunda encargada de la memoria.
Is Pornography Driving Men Crazy? - Naomi Wolf Exit from comment view mode. Click to hide this space NEW YORK – It is hard to ignore how many highly visible men in recent years (indeed, months) have behaved in sexually self-destructive ways. Of course, the heightened technological ability nowadays to expose private behavior is part of the reason for this change. What is driving this weirdly disinhibited decision-making? There is an increasing body of scientific evidence to support this idea. The hypothesis among the experts was that pornography was progressively desensitizing these men sexually. Given the desensitization effect on most male subjects, researchers found that they quickly required higher levels of stimulation to achieve the same level of arousal. Since then, a great deal of data on the brain’s reward system has accumulated to explain this rewiring more concretely. This is not to say that they are not responsible for their behavior.
wrapping up 2007 (28 December 2007, Interconnected) Wrapping up 2007: As Borges wrote reviews of non-existent books, I have notes for essays I'll never write. Here I've collected what's been on my mind the last couple of months. The common theme of Web 2.0 Expo Berlin was surfaces, which I picked up primarily from a talk on microformats as nanotech by Jeremy Keith and a conversation with Terry Jones. In short: the surface of the Web is currently pages - these are the atoms - which are interlinked (Tom Coates talks about how to be native to the Web of data). Search engines index the text, and our browsers make local deductions from the raw source to show rendered pages. What microformats and other forms of structure do is increase the resolution of the Web: each page becomes a complex surface of many kinds of wrinkles, and by looking at many pages next to each other it becomes apparent that certain of these wrinkles are repeated patterns. So what does phenotropics mean for the Web? The macro investigation is like chemistry.
