\"\"Cient\u00edficos hallaron que una regi\u00f3n qu\u00edmica del cerebro implicada en sistemas sensoriales y de recompensa es crucial para olvidar el dolor por las p\u00e9rdidas financieras. <\/p>\n

Los cient\u00edficos dicen que el estudio se\u00f1ala el camino para el posible desarrollo de f\u00e1rmacos que traten los problemas de los lud\u00f3patas y arroja luz sobre qu\u00e9 pudo suceder en los cerebros de los operadores de Wall Street y de la Ciudad de Londres durante la crisis financiera del 2008. <\/p>\n

\u00abLa ludopat\u00eda que sucede de forma regular en los casinos es lo suficientemente mala, pero creo que tambi\u00e9n se produce mucho ahora en el casino de Wall Street y el casino de la Ciudad de Londres\u00bb, dijo Julio Licinio, editor de la revista Molecular Psychiatry que revis\u00f3 y public\u00f3 el estudio el martes. <\/p>\n

\u00abNos gustar\u00eda creer que todos tenemos libre albedr\u00edo y tomamos las decisiones que queremos, pero esto nos muestra que no es f\u00e1cil\u00bb, dijo en una entrevista telef\u00f3nica. \u00abMuchas personas tienen predisposici\u00f3n a tomar ciertos tipos de decisiones\u00bb, apunt\u00f3. <\/p>\n

Para el estudio, el equipo de cient\u00edficos encabezados por Hidehiko Takahashi de la escuela de medicina de la Universidad de Kioto, Jap\u00f3n, escane\u00f3 el cerebro de 19 hombres sanos con una tomograf\u00eda por emisi\u00f3n de positrones (PET) tras haber realizado una apuesta. <\/p>\n

El experimento mostr\u00f3 que un neurotransmisor, o mensajero qu\u00edmico, denominado norepinefrina o noradrenalina, es vital para la respuesta ante la p\u00e9rdida de dinero. <\/p>\n

Aquellos con bajos niveles de transmisores de norepinefrina ten\u00edan altos niveles de este qu\u00edmico en una parte crucial de su cerebro, lo que les llevaba a estar menos estimulados y ser menos sensibles al dolor de la p\u00e9rdida de dinero, seg\u00fan los cient\u00edficos. <\/p>\n

La gente con mayores niveles de estos transmisores y por lo tanto menores niveles de norepinefrina tienen lo que se conocen como \u00abaversi\u00f3n a las p\u00e9rdidas\u00bb y sufren una respuesta emocional m\u00e1s pronunciada a las p\u00e9rdidas en comparaci\u00f3n con las ganancias. <\/p>\n

La aversi\u00f3n al riesgo puede variar ampliamente seg\u00fan las personas, explicaron los cient\u00edficos. Mientras que la mayor\u00eda de la gente s\u00f3lo entrar\u00eda en una apuesta con dos posibles resultados si existen m\u00e1s posibilidades de ganar que de perder, las personas con la toma de decisiones alterada muestran una sensibilidad reducida a la posibilidad de perder dinero. <\/p>\n

\nBrain study finds what eases pain of financial loss<\/p>\n

Financial market traders and keen gamblers take note. Scientists have found that a chemical in the region of the brain involved in sensory and reward systems is crucial to whether people simply brush off the pain of financial losses.<\/p>\n

Scientists say the study points the way to the possible development of drugs to treat problem gamblers and sheds light on what may have been going on in the brains of Wall Street and City of London traders as the 2008 financial crisis took hold.<\/p>\n

\u00abPathological gambling that happens at regular casinos is bad enough, but I think it’s also happening a lot now at Casino Wall Street and Casino City of London,\u00bb said Julio Licinio, editor of the Molecular Psychiatry journal which reviewed and published the brain study on Tuesday.<\/p>\n

\u00abWe like to believe we all have free will and make whatever decisions we want to, but this shows it’s not so easy,\u00bb he said in a telephone interview. \u00abMany people have a predisposure to make certain kinds of decisions.\u00bb<\/p>\n

For the study, a team of researchers led by Hidehiko Takahashi of the Kyoto University graduate school of medicine in Japan, scanned the brains of 19 healthy men with positron emission tomography (PET) scans after they had completed a gambling task.<\/p>\n

The experiment showed that a neurotransmitter, or chemical messenger, called norepinephrine, or noradrenaline, is central to the response to losing money.<\/p>\n

Those with low levels of norepinephrine transporters had higher levels of the chemical in a crucial part of their brain – leading them to be less aroused by and less sensitive to the pain of losing money, the researchers found.<\/p>\n

People with higher levels of transporters and therefore lower levels of norepinephrine or noradrenaline have what is known as \u00abloss aversion,\u00bb where they have a more pronounced emotional response to losses compared to gains.<\/p>\n

Loss aversion can vary widely between people, the researchers explained. While most people would only enter a two outcome gamble if it were possible to win more than they could lose, people with impaired decision making show reduced sensitivity to financial loss.<\/p>\n","protected":false},"excerpt":{"rendered":"
