Almost everyone thinks talking alone is crazy, and when we do we make sure that no one is listening. However, it seems that this habit stimulates the brain and helps it to better concentrate on the task or problem to be solved, according to a study recently published in the Quarterly Journal of Experimental Pyschology.
Chronic cocaine use accelerates brain aging, according to a study from the Institute of Clinical Neuroscience at the University of Cambridge published in the journal Molecular Psychiatry. Specifically, magnetic resonance images reveal that the loss of brain gray matter is greater in people dependent on this drug than in the rest of the population.
Can you guess the future by scanning the brain? In a way, yes, according to a study just published in The Journal of Neuroscience. The authors have found a connection between brain responses in the nucleus accumbens - the reward center - and behavior.
A study carried out a few years ago by MIT scientists revealed that there are three components of food that strengthen synapses between neurons and increase cognitive abilities consumed for at least four weeks: choline, present in eggs; uridine monophosphate, contained in beets; and docosahexaenoic acid (DHA) from fatty fish.
An international team of researchers has located a gene that determines both brain size and intelligence. The study, published in Nature Genetics, has collected brain images from more than 20,000 people from around the world.
A neuroscientific study from the Downstate Medical Center of the State University of New York (USA) reveals that intelligence and concern are related to a shortage of choline in the subcortical white matter of the brain. The researchers conclude that both traits coevolved in humans.
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.
What do Barack Obama, Messi, Hugo Chávez and Iker Casillas have in common? They are all left-handed, like 15% of the world's population. In Spain, the latest statistics indicate that there are about 12% left-handed. Right-left dominance in some functions such as hearing (the ear that we put on the watch), vision (the eye that we put in the telescope), manual manipulation (the hand with which we write) or the foot (the foot with which we shoot a ball) is determined by genetic and environmental factors and is established around five years
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.
