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!
Megan Tschannen-Moran's Web Site Dr. Megan Tschannen-Moran is a professor of educational leadership at the College of William and Mary School of Education. She prepares prospective school leaders for K-12 building-level and central office positions in the Educational Policy, Planning, and Leadership program. Her research focuses on relationships of trust in school settings and how these are related to important outcomes such as the collective efficacy beliefs of a school faculty, teacher professionalism, and student achievement. 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).

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 Four Ways to Give Good Feedback When effectively administered, feedback is a powerful way to build knowledge and skills, increase skills, increase motivation, and develop reflective habits of mind in students and employees. Too often, however, the feedback we give (and get) is ineffectual or even counterproductive. Here, four ways to offer feedback that really makes a difference, drawn from research in psychology and cognitive science: 1. (MORE: Secrets of the Most Successful College Students) 2. A second risk identified by Deci is that learners will interpret feedback as an attempt to control them — for example, when feedback is phrased as, “This is how you should do it.” According to Deci, a third feedback condition that can reduce learners’ engagement is an uncomfortable sense of competition. (MORE: How to Use Technology to Make You Smarter) 3. Once a goal has been clearly specified, feedback can help learners see the progress they’re making toward that target. 4.
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.
Less Empathy Toward Outsiders: Brain Differences Reinforce Preferences For Those In Same Social Group An observer feels more empathy for someone in pain when that person is in the same social group, according to new research in the July 1 issue of The Journal of Neuroscience. The study shows that perceiving others in pain activates a part of the brain associated with empathy and emotion more if the observer and the observed are the same race. The findings may show that unconscious prejudices against outside groups exist at a basic level. The study confirms an in-group bias in empathic feelings, something that has long been known but never before confirmed by neuroimaging technology. "Our findings have significant implications for understanding real-life social behaviors and social interactions," said Shihui Han, PhD, at Peking University in China, one of the study authors. Other recent brain imaging studies show that feeling empathy for others in pain stimulates a brain area called the anterior cingulate cortex. But the finding raises as many questions as it answers, Farah said.
RFQ RFT RFP RFI - Procurement Processes Negotiation Experts - Tendering Clients and newsletter readers have asked that we demystify the meaning behind each of the following procurement terms: RFI, RFQ, RFT and RFP. These processes have steadily grown in popularity in procurement and purchasing, especially amongst larger buying organisations. Sadly proper training is often not given on which process to use and in how to effectively use each process. As a result, in practice you will find these phrases used interchangeably, as many organisations don’t understand the differences sufficiently, resulting in the buyers missing negotiation advantages. RFI – Request for Information An open enquiry that spans the market seeking broad data and understanding. RFQ – Request for Quotation An opportunity for potential suppliers to competitively cost the final chosen solution(s). RFT – Request for Tender An opportunity for potential suppliers to submit an offer to supply goods or services against a detailed tender. Request for Information (RFI) Request for Quotation (RFQ)
