Delirium, stroke or nerve damage: the neurological complications of Covid-19
Delirium, inflammation of the brain, stroke, and nerve damage. These are some of the neurological complications that can cause covid-19, according to a new study led by the University College London and the University College London Hospitals NHS Foundation Trust (Uk) that publishes the journal “Brain”.

2. Closer to hibernation human: it is already possible to achieve this in mice
A team of researchers from the japanese University of Tsukuba announced in Nature the discovery of specific cells in the brain of mice that can trigger a state similar to that of hibernation when they are activated. And the mice do not form part of the group of animals that hibernate in a natural way. The information, here.
3. The strange case of the man who can’t see the numbers
RFS, those are your initials, is an individual of 70 years of age with a brain anomaly unique in the world. Can not recognize the numbers 2 to 9. When shown a digit, only sees a mix of lines that are described as “spaghetti” and not have the slightest idea of what digit you’re looking at. Moreover, his vision is normal. For example, can identify letters and other symbols. The cause is an atrophy extensive in the cortex and the basal ganglia.
For the researchers of Johns Hopkins University in Baltimore, Maryland (USA), RFS shows that we humans have a processing extensive brain without any awareness. That is to say, that our brain can identify something as a face or a word without us to realize. The news, here.
4. The path to the brain of the language, since 20 million years ago
An international team of researchers has just discovered that the evolutionary origins of language can be traced, as minimum, to 20 million years ago, much further back in time than was thought until now. Of course, that doesn’t mean that that time, that was not yet human, some far ancestor had the ability to speak, but the brain pathways that much later would allow the talks were already present. Until now, it was believed that these routes had emerged much later, about 5 million years ago, in some common ancestor between apes and humans. Continue reading.
5. The brain waves that reveal that you are being selfish
A study that has been published in “Nature Neuroscience” has been able to demonstrate, for the first time, that the activity of the brain changes significantly when you commit a selfish act or one altruistic. In particular, researchers have observed in a few experiments in which monkeys were faced with the dilemma of whether to share or not a fruit juice. Read the full story here.
6. The part of the brain that distinguishes us from the neanderthals
A team of Paleoneurobiología of the National Research Center on Human Evolution (CENIEH), directed by Emiliano Bruner, has discovered that the brain of modern man has two most developed areas in comparison with that of the neanderthals. The first is the back and dorsal superior parietal lobule, and the second, the middle area of the intraparietal sulcus, in the inferior parietal lobe. It turns out that these areas are related to the skills visoespaciales that, among other things, allow for the imagination impaired, the management of space and time, the creation of tools and even social relations, aspects that define us as a species. The results also explain the more round form of our brain. The information, to the detail.
7. A woman plays the violin while he removed a tumor in the brain
Play the violin while you removed a brain tumor in the operating room. That is what made Dagmar Turner, 53 years of age, a patient of King’s College Hospital, London. With this technique, which is not new, although very striking, and the surgeons ensure not to damage the areas of the patient’s brain responsible for movement and coordination of the hands, a crucial component when playing the said instrument.

8. Described for the first time emotions in the face of mice
researchers have described for the first time the different expressions of emotion on the faces of the mice. In a similar way as happens with the human, the face of a mouse looks completely different when something tastes sweet or sour, or when you feel anxious. This finding, released in the journal “Science”, could shed light on the basic principles of how to generate and process emotions in the brain. More about this study, here.
9. Your brain changes when you eat
A team of researchers has revealed what is the mechanism that activates the satiety right after eating. Their study, which has been published in “Cell Reports” and that has been developed with mice, shows that it produces a cascade of reactions after that increase the levels of glucose in the blood. The information, here.
10. How the piece of brain of a decapitated has survived intact 2,600-year
A man was beheaded near the present town of York (United Kingdom) makes it 2600 years. You don’t know the reasons, but his head -just his head – was quickly buried in a soil rich in clay. And there it remained until 2008, at which time researchers from the York Archaeological Trust found the skull. The study, appeared the surprise: a piece of what looked like the brain of the man was in his inner. A finding is very rare, as it is one of the organs that first degrades after death. Read here how it has been possible.
