Silence helps regenerate the brain..?

Until recently it was thought that neurons could not regenerate and that our brain was sentenced to a progressive and inexorable decline. However, with the discovery of neurogenesis everything has changed, neuroscientists now focus on discovering what can promote neuronal regeneration. In this regard, a group of German researchers at the Research Center for Regenerative Therapies Dresden have discovered that silence has a huge impact on the brain. These scientists found that in the brains of mice remained silent for two hours every day growing new cells in the hippocampus, the brain region involved in memory, emotion and learning. In addition, they found that these new cells were able to differentiate and integrate into the central nervous system to fulfill different functions. Therefore, reserve a few minutes a day to be in complete silence could be very beneficial for our brain, helping to preserve the memory and to be more flexible to changes. Silence allows the brain gives meani

Dunning-Kruger syndrome

The relationship between stupidity and vanity described as the Dunning-Kruger effect, whereby people with little intellectual and cultural level systematically tend to think they know more than what they know and to be considered more intelligent than they are. The phenomenon was rigorously studied by Justin Krugger and David Dunning, psychologists at Cornell University in New York, and published in 1999 in "The Journal of Personality and Social Psychology" It is based on the following principles: 1. Incompetent individuals tend to overestimate their own abilities. 2nd. Incompetent individuals fail to recognize the true abilities in others. The advance of Krugger and Dunning was simply prove in an experiment consisting of measuring the intellectual and social skills of a number of students and ask a self-assessment later. The results were surprising and revealing: the brightest felt they were below average; mediocre considered above average, and the less gifted and mo

anthocyanins

Anthocyanins are a group of pigments red, water-soluble, colored widely distributed in the plant kingdom. chemically Anthocyanins are glycosides of anthocyanidins, is you say, are constituted by a molecule of anthocyanidin, which is the aglycone, which is joined a sugar by a glycosidic bond β-. The basic chemical structure of these aglycones is ion flavylium. also called 2-fenilbenzopirilio , Consisting of two groups aromatic: one benzopyrilium and a phenolic ring; he flavylium normally functions as a cation. The free aglycones rarely exist in food, except possibly as components trace degradation reactions. They represent the major anthocyanins soluble pigments visible to the human eye water. They belong to the group of flavonoids and structure Basic is a flavone core, which consists of two aromatic rings linked by a unity of three carbons He sugar present in the molecule gives them great solubility and stability, generally joins the anthocyanidin at the 3 pos

La  quercetina  ( f òrmula molecular:  C 15 H 10 O 7 ) es un flavonol que se encuentra presente generalmente como O - glicósidos y raramente como C - glicósidos en altas concentraciones tanto en  f rutas como en  v erduras en especial en la  c ebollas. Muchas plantas, ya sean consideradas medicinales o no, deben gran parte de sus beneficios a los altos niveles de quercetina que presentan. Por ejemplo, algunas clases de cebolla (como la roja) contienen tanta quercetina que el compuesto representa el 10% de su peso seco. . Un estudio realizado  in vitro  mostró que la quercetina y el  r evesratrolcombinados inhiben la producción de cèlulas adiposas. Quercetin (molecular formula: C15H10O7) is a flavonol that is present generally as O - glycosides and rarely as C - glycosides in high concentrations in fruit and both vegetables particularly in onions. Many plants, whether or not considered medicinal, owe much of their profits to high levels of quercetin they present. For example, som
