Can talking to young children during TV time buffer screen time effects on development?

Added: 12.11.2021 14:10 | 219 views | 0 comments

The more parents engaged in conversation with preschoolers during shared TV time, the more likely those children were to have higher curiosity levels when they reached kindergarten, a new study suggests. This was particularly true for children with socioeconomic disadvantages.

Gene therapy boosts Parkinson’s disease drug benefits

Added: 12.11.2021 8:46 | 509 views | 0 comments

A new gene therapy targeting the small brain region where dopamine neurons reside, the substantia nigra, substantially boosts the benefits of the drug levodopa in Parkinson's. The therapy restored the ability of these neurons to convert levodopa to dopamine. Scientists also showed how damage to the powerplants inside dopamine-releasing neurons triggers Parkinson's. The findings may help identify humans in the earliest stages of Parkinson's disease, develop therapies to slow disease progression and treat late-stage disease.

Using mechanical tools improves our language skills, study finds

Added: 11.11.2021 20:42 | 232 views | 0 comments

Research has revealed a correlation between being particularly proficient in tool use and having good syntactic ability. A new study has now shown that both skills rely on the same neurological resources, which are located in the same brain region. Furthermore, motor training using a tool improves our ability to understand the syntax of complex sentences and -- vice-versa -- syntactic training improves our proficiency in using tools.

When mom and child interact, physiology and behavior coordinate

Added: 11.11.2021 18:03 | 237 views | 0 comments

When mothers and their children play together, they instinctively respond to each other's cues. And positive interactions promote the child's healthy socioemotional development. A new study examines how physiological and behavioral reactions coordinate during mother-child playtime. The findings highlight the importance of responsive communication, and can help provide insights for parents, practitioners, and researchers.

This is how we understand emoji

Added: 11.11.2021 18:02 | 227 views | 0 comments

Even when emoji are used to substitute for words, we still understand the sentence. But how does that work? Do we interpret an emoji primarily as an image or as a word? To find out, a research team asked volunteers to read texts with emoji and measured the reading time precisely. It turns out that it takes a little longer to comprehend a sentence that includes emoji than one that doesn't. If the emoji does not directly represent the intended meaning, but another word with the same pronunciation, we need yet a little more time. Based on these results, the team concludes that emoji comprehension consists of two steps: first the image is interpreted, then the word is inferred.

Function of mysterious structure found on neurons

Added: 11.11.2021 13:04 | 224 views | 0 comments

Researchers have discovered that mysterious clusters of proteins found on neurons are calcium-signaling 'hotspots' that activate gene transcription, allowing neurons to produce crucial proteins. The discovery may help shape new research into the role of the hotspots in brain function and potentially lead to new classes of therapeutics.

Students who self-identify as multilingual perform better in exams

Added: 11.11.2021 13:03 | 232 views | 0 comments

Young people who consider themselves 'multilingual' tend to perform better across a wide range of subjects at school, regardless of whether they are actually fluent in another language, new research suggests. The study of more than 800 pupils in England found a measurable, positive relationship between their personal connection with other languages, and their GCSE exam results in both modern language and non-language subjects. This applied whether or not they actually spoke a second language fluently.

Mosaic brain evolution in guppies helps to explain vertebrate cognitive evolution

Added: 10.11.2021 19:55 | 219 views | 0 comments

Researchers have provided the first experimental evidence that brain regions can evolve independently of each other during cognitive evolution. This so called mosaic brain evolution was verified empirically in an artificial selection experiment with guppies (Poecilia reticulata) where telencephalon size (but no other regions) differed by 10 percent after only four generations of selection. The findings can have wide implications for the understanding of cognitive evolution in other vertebrates, such as primates and humans.

Zika virus-specific therapy protects the fetal mouse brain

A gene-silencing therapy protected against Zika virus transmission from pregnant mice to the mouse fetuses, finds a new study. The treatment, which harnesses nanoparticles called small extracellular vesicles (sEVs) for drug delivery, crossed the placenta and blood-brain barrier to greatly reduce fetal neurological damage, including virus-induced brain shrinkage.

Human neurons have a lower density of ion channels than expected, compared to neurons of other mammals, according to a new study. The researchers hypothesize that a lower channel density may have helped the human brain evolve to operate more efficiently.
