| Potential indicator for obesity risk detected during sleep Posted: 09 Sep 2021 09:40 AM PDT Researchers have shown that people with inflexible metabolisms burn less fat at night than those with flexible metabolism. The team measured the respiratory quotient throughout the night and found that despite equal ages, BMIs, and amount of fat, people with inflexible metabolisms burned more carbohydrates and less fat than did people with flexible metabolisms. The higher sleep-time quotient could be a previously unknown indicator for the risk of future metabolic disease. |
| Disease genes help developing brains Posted: 09 Sep 2021 09:39 AM PDT If the cerebral hemispheres of the forebrain fail to divide properly in an unborn child, this results in holoprosencephaly. A team has discovered candidate genes that can positively influence the severity of this congenital malformation of the forebrain. |
| Office air quality may affect employees’ cognition, productivity Posted: 09 Sep 2021 09:39 AM PDT The air quality within an office can have significant impacts on employees' cognitive function, including response times and ability to focus, and it may also affect their productivity, according to new research. |
| Learning by doing: How the brain's motor system can support vocabulary learning Posted: 09 Sep 2021 09:39 AM PDT Neuroscientists present new findings on how the motor cortex can help learn foreign vocabulary more quickly. The new data suggests that learning techniques that involve the performance of gestures instead of simple audio or visual information can benefit learners. |
| Behind the scenes, brain circuit ensures vision remains reliable Posted: 08 Sep 2021 03:06 PM PDT As mice watched movies, neuroscientists watched their brains to see how vision could be represented reliably. The answer is that consistency in representation is governed by a circuit of inhibitory neurons. |
| Limiting screen time for young adults after concussion results in shorter duration of symptoms Posted: 08 Sep 2021 03:06 PM PDT Newly published research shows that young adults who limited screen time for 48 hours immediately after suffering a concussion had a significantly shorter duration of symptoms than those who were permitted screen time. |
| What the brain shows: The benefits of virtual reality in creative arts therapies Posted: 08 Sep 2021 03:05 PM PDT Researchers examined the differences in prefrontal cortex (PFC) activation between two distinct drawing tasks in virtual reality. Results of the study indicated significant differences between a rote tracing task and a creative self-expression task, with the rote tracing task showing an increase in PFC activity. It also showed there was reduced PFC activation for creative self-expressive tasks, indicating a possible relaxation response. |
| People with Parkinson's may benefit from seven walking strategies Posted: 08 Sep 2021 03:05 PM PDT Various strategies can help people with Parkinson's who have difficulty walking, but a new study finds that many people have never heard of or tried these strategies. The study also found that how well different compensation strategies worked depended on the context in which they were used, such as indoors versus outdoors, under time pressure or not. |
| Good sleep-time recovery is associated with a healthier diet and lower alcohol consumption Posted: 08 Sep 2021 03:04 PM PDT Good sleep-time recovery is associated with a health-promoting diet and health-promoting eating habits, as well as with lower consumption of alcohol, according to a new study investigating psychological and physiological well-being among working-age Finnish adults. |
| New information on the early stages of dementia with Lewy bodies Posted: 08 Sep 2021 03:04 PM PDT Results from a new study reinforce the notion that dementia with Lewy bodies can be pathologically classified into two different disease types. |
| Massage stones help scientists uncover role of prefrontal cortex in sensory perception Posted: 07 Sep 2021 08:07 AM PDT An image of a beautiful beach conjures up certain sensations -- one can imagine the sun's warmth and the sound of waves breaking on the shore. But how is it that the brain produces these impressions when someone isn't actually standing on a beach? Using massage stones, pictures of sunny beaches and snowy landscapes, and sounds of noisy cities and quiet forests, research suggests the prefrontal cortex generalizes perceptual experiences from information received through different senses. |
