Técnica com ultrassom

O glioblastoma é o tipo de tumor primário mais comum no cérebro, altamente agressivo e maligno. Pacientes com esse tipo de câncer geralmente são submetidos a ressecção seguida de radioterapia e quimioterapia. Apesar do tratamento, a sobrevida é de 12 a 18 meses a partir da data do diagnóstico. Novos tratamentos têm sido desenvolvidos e um deles tem se mostrado promissor. O estudo da referência aborda uma técnica que envolve a aplicação de ultrassom focal na região tumoral através do crânio intacto associada à aplicação de uma substância que sensibiliza as células para os efeitos prejudiciais do som. A terapia sonodinâmica representa uma grande promessa para o tratamento de cânceres que se espalharam para áreas sensíveis do corpo (metástases) e, em particular, do cérebro. 📑♒🧠Este tema será abordado no módulo Tratamento & Reabilitação do Cérebro da @mybrainuniversity

Neurocientistas avaliaram as conexões cerebrais em associação aos índices de criatividade mensurados por testes psicológicos. Eles não encontraram diferenças estatísticas na conectividade dentro dos hemisférios ou entre homens e mulheres. Entretanto, quando compararam as pessoas que pontuaram nos 15% superiores nos testes de criatividade com as dos 15% inferiores, aquelas com maior pontuação tiveram significativamente mais conexões entre os hemisférios direito e esquerdo. As diferenças estavam principalmente presentes entre os lobos frontais do cérebr. 🧠💡💭 Este tema será abordado no módulo Cognição & Funções Executivas da @mybrainuniversity

In a Crisis, Pessimism Is Natural but Realism Is Crucial

It is important to recognize our pessimistic predispositions, so we may overcome them. When you read the news, make sure that in addition to reading about the latest COVID-19 death count, you also ingest the latest technological, medical and scientific breakthroughs that will bring the pandemic to an end.

With the COVID-19 lockdown upon us, anxiety and depression are on the rise. It would be irresponsible to downplay the risks that coronavirus poses to America’s health and economy. But excessive pessimism is also in no one’s interest. Problems and their purported solutions must be evaluated coolly and dispassionately. Facts, logic, reason and science, not emotions, must guide us in this time of troubles.

Unfortunately, some of our most basic impulses evolved at a time when the world was very different from our own. Our modern skulls house a stone age mind,” note Leda Cosmides and John Tooby from the University of California, Santa Barbara. The mind can be decidedly harmful in helping us address today’s problems, including those of anxiety and depression.

Overcome your fear factor

Fear and worry got you down? Here’s how to calm these feelings.

Have you grown more worried and fearful about life over the years? You aren’t alone. Research has shown that feelings of fear, general anxiety, and nervousness tend to rise with age.

These negative feelings can manifest in many ways. You could be more concerned about your financial future, the risk of a new or returning health problem or injury, or as the recent COVID-19 pandemic has shown, changes in world events.

“People become more fearful about daily life because they worry a setback will come at any time, and it’s something they can’t control,” says Dr. Ipsit Vahia, medical director of Geriatric Psychiatry Outpatient Services at Harvard-affiliated McLean Hospital.

Centenarian study suggests living environment may be key to longevity

When it comes to living to the ripe old age of 100, good genes help, but don’t tell the full story. Where you live has a significant impact on the likelihood that you will reach centenarian age, suggests a new study conducted by scientists at Washington State University’s Elson S. Floyd College of Medicine.

Published in the International Journal of Environmental Research and Public Health and based on Washington State mortality data, the research team’s findings suggest that Washingtonians who live in highly walkable, mixed-age communities may be more likely to live to their 100th birthday. They also found to be correlated, and an additional analysis showed that geographic clusters where the probability of reaching age is high are located in and smaller towns with higher socioeconomic status, including the Seattle area and the region around Pullman, Wash.

The synchrony between neurons in different brain hemispheres could aid behavioral adaptation

In order to survive and thrive, humans and other living organisms must continuously acquire new strategies to adapt their behavior to changing environments. Past studies suggest that the synchronization between different brain cells could create flexible brain states that facilitate behavioral adaptation to different situations.

Organisms have often been found to exhibit rhythmic neural activity that simultaneously occurs in different parts of the brain in a synchronized fashion. However, neuroscientists have not yet been able to determine whether this synchronized activity is important for specific brain functions or is merely a by-product of the way in which brain circuits are organized.
