La curiosité n'est pas un « vilain » défaut chez les souris Dans notre quotidien, nous sommes fréquemment confrontés à des prises de décision. Quand il s'agit de choisir entre différentes options, celles-ci peuvent être sures et connues, ou bien plus incertaines. Estimer le « degré d'incertitude » associé à ces alternatives est indispensable pour prendre une décision adaptée. Cette évaluation joue sur notre motivation à tenter des actions aux conséquences incertaines, à être curieux. Elle peut aider à mieux connaître notre environnement et ainsi améliorer la réussite des actions futures. Jusqu'à présent, la manière dont l'évaluation de l'incertitude était régulée restait méconnue. Première étape : les souris étaient placées dans une arène constituée de trois zones, chacune d'elle étant corrélée à l'obtention d'une récompense. Ces résultats établissent clairement le rôle de l'acétylcholine dans la motivation induite spécifiquement par l'incertitude du résultat. © Naudé, Faure (CNRS/UPMC/Inserm) Télécharger le communiqué de presse : Notes :

Getting to the root of Latvian philosophy RIGA - In a recent poll to find 100 important Latvian personalities, Teodors Celms made a somewhat surprise showing on the list. Celms was that rarest of things in Latvia 's a professional philosopher. Although his heyday was in the 1920s and 1930s, he still remains arguably the only homegrown philosopher of any real significance. But what is his legacy, if any? Does philosophy even have a role to play in society beyond the lecture rooms of the University of Latvia's faculty of philosophy? TBT set out to investigate the state of things. Celma has been teaching esthetics and Russian philosophy at the University of Latvia for almost 40 years. The associate professor doesn't appear especially interested in discussing her grand uncle's achievements, although she frequently references him in her lectures. "Latvia doesn't have any great philosophers," Celma muses. Maija Kule, for one, believes there is. "Teodors Celms was our best philosopher," Kule explains.

Partes y funciones del cerebro humano Sistema Nervioso El sistema nervioso está constituido por el tejido nervioso del organismo y los elementos de soporte asociados. Desde un punto de vista estructural o anatómico, el sistema nervioso se divide en dos; el Sistema Nervioso Central (SNC) y el Sistema Nervioso Periférico (SNP). Por otro lado, desde el punto de vista funcional el sistema nervioso se divide, en Sistema Nervioso Somático y Sistema Nervioso Autónomo. La función del sistema nervioso consiste en recibir los estímulos que le llegan tanto del medio externo como interno del organismo, organizar esta información y hacer que se produzca la respuesta adecuada.

Elon Musk: The World's Raddest Man This is Part 1 of a four-part series on Elon Musk’s companies. PDF and ebook options: We made a fancy PDF of this post for printing and offline viewing (see a preview here), and an ebook containing the whole four-part Elon Musk series: Last month, I got a surprising phone call. Elon Musk, for those unfamiliar, is the world’s raddest man. I’ll use this post to explore how he became a self-made billionaire and the real-life inspiration for Iron Man’s Tony Stark, but for the moment, I’ll let Richard Branson explain things briefly: Whatever skeptics have said can’t be done, Elon has gone out and made real. So no, that was not a phone call I had been expecting. A few days later, I found myself in pajama pants, pacing frantically around my apartment, on the phone with Elon Musk. For me, this project was one of the biggest no-brainers in history. – “electric vs hybrid vs gas cars, deal with tesla, sustainable energy” – “spacex, musk, mars?? So it was on. Zeus would have been less stressful. Mm hm.

Philosophy in the Soviet Union From the beginning of Bolshevik regime, the aim of official Soviet philosophy (which was taught as an obligatory subject for every course[source?]), was the theoretical justification of Communist ideas. For this reason, "Sovietologists", among whom the most famous were Józef Maria Bocheński, professor of philosophy at the Pontifical University of Saint Thomas Aquinas and Gustav Wetter, have often claimed Soviet philosophy was close to nothing but dogma. However, since the 1917 October Revolution, it was marked by both philosophical and political struggles, which call into question any monolithic reading. Evald Vasilevich Ilyenkov was one of the main philosophers of the 1960s, who revisited the 1920s debate between "mechanicists" and "dialecticians" in Leninist Dialectics and Metaphysics of Positivism (1979). Philosophical and political struggles in the Soviet Union[edit] Otherwise, David Riazanov was named director of the Marx-Engels Institute, which he had founded, in 1920.

Make Beliefs Comix Investigador en geriatría derriba mitos sobre el deterioro mental en la vejez "El mito más grande que se nos ha dicho sobre la mente en el adulto mayor es que el deterioro cognitivo no puede tratarse, que es irreversible y que es parte del envejecer. No hay pastillas para tratarlo, pero sí hábitos que pueden mejorar el pronóstico". Así sostiene el investigador John Morley, de la Universidad de San Luis en Misuri, Estados Unidos, quien se encuentra en Costa Rica para participar como conferencista de la Semana Nacional de la Geriatría, actividad organizada por el Hospital Nacional de Geriatría. Durante más de dos décadas él ha estudiado, desde su universidad y desde la práctica clínica, intervenciones que pueden realizarse de manera temprana con las personas para evitar un deterioro cognitivo mayor e, incluso, mejorar su funcionalidad. La Nación conversó con él sobre los mitos, como el anterior, y algunas dudas que existen con respecto a este trastorno neurodegenerativo y cómo podemos, desde nuestro metro cuadrado, prevenirlo o hacer más lentas sus manifestaciones.

Secrets From The Brains Of 13 Creative Geniuses In 1963, Nancy Andreasen was the first female tenure-tracked English professor at the University of Iowa. Soon after, her first book about the poet John Donne was accepted by a publisher. Her career was off to a smashing start, but she had a nagging feeling. "Who would this book help?" Within a month, she enrolled in the medical school at the University of Iowa. In her latest study, which she recently wrote about for the Atlantic, Andreasen scanned the brains of 13 of the most famous scientists, mathematicians, artists, and writers alive today. The study was challenging given how hard it is to pin down the creative process. Andreasen had to find a way to study these creative minds at work. In her findings she has distilled some key patterns in the minds of creative geniuses. Creative people like to teach themselves rather than be taught by others. Think of all the creative geniuses who were high school drop-outs—Bill Gates, Steve Jobs, Mark Zuckerberg.

Criminology word list - Vocabulary List El cerebro lector: algunas ideas clave Cuanto antes se automatice la lectura, más podrá el niño concentrar su atención en comprender lo que lee y volverse así un lector autónomo, tanto para aprender otras cosas como para su propia diversión. Stanislas Dehaene La lectura constituye una de las actividades más asequibles para mantener una buena salud cerebral porque en ese proceso intervienen muchas funciones cognitivas diferentes, como la percepción, la atención, la memoria o el razonamiento. Al leer, se activa una gran cantidad de circuitos neuronales y regiones concretas del cerebro (ver figura 1) que nos permiten, en milésimas de segundo, reconocer las letras, combinarlas para formar grafemas y palabras, asignarles sonidos para poder pronunciarlas y dotarlas de significado. El aprendizaje de la lectura es una de las áreas de investigación en neurociencia que ha suministrado más información novedosa con implicaciones pedagógicas en los últimos años.

Facing Chaos? Focus on What You CAN Control | Daniel Goleman Varying Theories on Crime | Regis University Many theories have been developed to explain criminal behavior. While some theories are not as common, others have evolved and are used in many criminal studies today. Modern criminologists combine the most germane aspects of sociology, psychology, anthropology, and biological theories to advance their understanding of criminal behavior. Criminal Behavior Theories Professionals in this field study the factors that contribute to criminal activities, make relevant policy recommendations and draw conclusions based on those assessments. Historical Philosophies Though crime studies have advanced beyond its field-specific foundations, the core ideas of these early philosophies are still applied to current theories. Current Theories Current theories retain the essence of their roots while expanding beyond antiquated or limiting concepts. Rational Choice Theory, founded in Classical Theory, cites three “actors” (rational, predestined, and victimized) as the models for criminal behavior.
