How the brain processes sign language
Over 70 million deaf people use sign languages as their preferred communication form. Although they access similar brain structures as spoken languages, it hasn't been identified the brain regions that process both forms of language equally. MPI CBS has now discovered that Broca's area in the left hemisphere, central for spoken languages, is also crucial for sign languages. This is where the grammar and meaning are processed, regardless of whether it is spoken or signed language. (2021-02-19)

They have now published their findings in 'Physical Review X'. (2021-02-18)

The distribution of vertebrate animals redefines temperate and cold climate regions
The distribution of vegetation is routinely used to classify climate regions worldwide, yet whether these regions are relevant to other organisms is unknown. Umeå researchers have established climate regions based on vertebrate species' distributions in a new study published in eLife. They found that while high-energy climate regions are similar across vertebrate and plant groups, there are large differences in temperate and cold climates. (2021-02-18)

How the 'noise' in our brain influences our behavior
The brain's neural activity is irregular, changing from one moment to the next. To date, this apparent ''noise'' has been thought to be due to random natural variations or measurement error. However, researchers at the Max Planck Institute for Human Development have shown that this neural variability may provide a unique window into brain function. (2021-02-17)

Where and when is economic decision-making represented in the brain?
Researchers at the University of Tsukuba report two areas of the monkey brain that represent expected value when making economic decisions. Analyses showed that neuronal activity in the VS and the cOFC provided stable representations of expected value, while other regions that are part of the reward network in the brain did not. State-space analysis revealed that the way expected value was represented over time differed in these two areas. (2021-02-10)

Study: Diabetes complications in young children target the brain
Brain volume, verbal IQ, and overall IQ are lower in children with Type 1 diabetes (T1D) than in children without diabetes, according to a new longitudinal study published in Diabetes Care, a journal of the American Diabetes Association. The nearly eight-year study compared brain scans of young children who have T1D with those of non-diabetic children to assess the extent to which glycemic exposure may adversely affect the developing brain. (2021-02-10)

Mediterranean-style diet linked to better thinking skills in later life
People who eat a Mediterranean-style diet--particularly one rich in green leafy vegetables and low in meat--are more likely to stay mentally sharp in later life, a study shows. Closely adhering to a Mediterranean diet was associated with higher scores on a range of memory and thinking tests among adults in their late 70s, the research found. The study found no link, however, between the Mediterranean-style diet and better brain health. (2021-02-10)

Adult neurogenesis may hold clues for more effective treatment of alcoholism
Neuroplasticity, the remarkable ability of the brain to modify and reorganize itself, is affected by or in response to excessive alcohol, whether through individual consumption or exposure in the womb. It is now well accepted that the birth and integration of new neurons continue beyond development and into adulthood. New discoveries and insights on how alcohol impacts this and other plastic processes are discussed in ''Alcohol and Neural Plasticity,'' a special issue of Brain Plasticity. (2021-02-10)

Traumatic stress in childhood can lead to brain changes in adulthood: study
A new study has shown that traumatic or stressful events in childhood may lead to tiny changes in key brain structures that can now be identified decades later. The study is the first to show that trauma or maltreatment during a child's early years--a well-known risk factor for developing mental health conditions such as major depressive disorder in adulthood--triggers changes in specific subregions of the amygdala and the hippocampus. (2021-02-09)

Can the brain resist the group opinion?
Scientists at HSE University have learned that disagreeing with the opinion of other people leaves a 'trace' in brain activity, which allows the brain to later adjust its opinion in favour of the majority-held point of view. The article was published in Scientific Reports. (2021-02-08)

Climate change: Erratic weather slows down the economy
If temperature varies strongly from day to day, the economy grows less. Through these seemingly small variations climate change may have strong effects on economic growth. This shows data analyzed by researchers from the Potsdam Institute for Climate Impact Research (PIK), Columbia University and the Mercator Research Institute on Global Commons and Climate Change (MCC). In a new study in Nature Climate Change, they juxtapose observed daily temperature changes with economic data from more than 1,500 regions worldwide over 40 years - with startling results. (2021-02-08)
