List Of Small Legendary Pokemon
Well, as I promised this time we will review an article by James K. Rilling, David A. Gutman, Thorsten R. Zeh, Giuseppe Pagnoni, Gregory S. Berns and Clinton D. Kilts, Emory University, where he reported his studies on the neural basis of social cooperation, which was published in 2002 in the journal Neuron.
In this study the authors used a task that has been widely used to study social cooperation. It is a task that is called "The iterate Prion's dilemma game" or in English would be something like "The play iterated prisoner's dilemma. " This problem is as follows: Suppose you are arrested with a colleague of yours, on suspicion of having committed a crime. Each one is in an interrogation room answering questions from detectives. Then one of the police case manager invites you to involve your partner as the one who committed the crime. What happens with you two will depend on what each of you respond to the police. If your partner betrays you implicándote to you while you remain silent, then you will get a big sentence, as he will go free, and vice versa, if you so imply, then you will go free and receive a long sentence. Now, if they decide to cooperate with you and do not engage each other, then both receive a light sentence. But if both have testified against the other, then receive a sentence greater than that of when silent, but would receive less than one when the other was released, as in the table below (taken from: http: / / www.iterated-prisoners-dilemma.net/ ).

Well, Rilling and colleagues applied this task 36 women while functional images obtained by functional magnetic resonance imaging. Once the images were analyzed and found that mutual cooperation was associated with consistent activation of brain areas that have been associated with processing of rewards, such as the nucleus accumbens, caudate nucleus, ventromedial cortices, orbitofrontal and anterior cingulate cortex. This finding led them to these authors propose that activation of this network of neural areas associated with reward, positive reinforcement altruism, leading to a motivation for subjects to resist the selfish temptation to accept police officer's offer to betray his partner to not correspond to the attitude of better remain silent.
Scheme activities in two areas related to social cooperation (anteroventral nucleus accumbens and striatum).
Although I do not want to get a shirt of eleven staff, I have to say that the study suggests that when you perform an action of social cooperation in the win-win (and not just you) is allowed to come on dopaminazo producing a reinforcing effect that eventually leads to an increase of conduct for society. How about, uh, and I thought that this circuit only served to encourage strengthening my lower passions, as when he encouraged me to go to my favorite restaurant to eat the beef tenderloin which, unfortunately, comes in a pretty penny!.
We do not hold me wanting to put a picture of the scene from the movie "The Matrix" where Cypher prefer your virtual dopaminazo obtained by eating a juicy steak, the social reward not betray Morpheus.
