Scientists have spent years observing with the help of scanners how and when the pleasure circuit is activated in the human brain. "As is logical to suppose, this circuit is activated by 'vicious' stimuli such as orgasm, the intake of sweet and fatty foods, financial rewards and some psychoactive substances (tobacco, drugs ...)", explains neuroscientist David J. Linden. These experiences cause the release of dopamine in a series of brain regions (nucleus accumbens, prefrontal cortex, dorsal striatum and amygdala) that generate a pleasant sensation, and the acts that have preceded or coincided with them end up being associated with positive memories and sensations.
Playing soccer doesn't just require good muscles and some skill with the ball. The higher the division in which a soccer player plays, the greater their cognitive abilities, say researchers from the Karolinska Institute in Stockholm in a study published in the journal PLoS One.
A study by the Pablo Olavide University of Seville has shown that applying weak currents through the skull modifies the learning of simple motor tasks, accelerating or interrupting this process depending on the polarity of the applied current. The results are published in the journal 'PNAS'.
A team of researchers has managed to partially manipulate the memories of several laboratory mice, according to the journal Science. This work, in addition to helping neuroscientists better understand memory formation processes, could be useful in treating schizophrenia or post-traumatic stress symptoms.
Yes. Specifically, the prefrontal cortex, a region of the brain located above the eyes, is larger the greater the number of friends we have, according to a British study published in the journal Proceedings of the Royal Society B.
Is the saying that two heads are better than one true? At least when it comes to solving problems and making decisions, yes, according to a recent study carried out at the University of Aarhus (Denmark) and the University College London (United Kingdom). Although, according to the researchers published in 'Science', this is only true if both people are equally competent and able to reach an agreement after reasonably discussing the problem.
A recent study claims yes. Human replicas resemble and act almost like human beings, but they elicit feelings of displeasure. The perceptual mismatch between appearance and movement could be causing these feelings.
A few years ago, a study published in the journal Nature Neuroscience revealed that it is possible to identify whether a person has racist prejudices using a scanner and showing them portraits of subjects with different skin color. Its author, the neuroscientist Jennifer Richeson, explained that the system serves to detect racist attitudes, but does not imply any type of behavior, since people can be impartial despite the fact that their mental activity indicates that they have some type of racial prejudice, that it may or may not be intentional.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
