| Ever been lost in the grocery store? Researchers are closer to knowing why it happens Posted: 16 Nov 2021 02:47 PM PST A new study suggests that the brain differentiates very similar environments -- such as two stores from the same supermarket chain -- as if they were even more different than two places that are nothing alike. |
| Posted: 16 Nov 2021 12:23 PM PST Using a new model of brain activity, computational neuroscientists are exploring striking bursts of activity in the human brain that have not been examined before. These bursts may have potential to serve as biomarkers for brain disease and conditions such as depression, schizophrenia, dementia, and ADHD. |
| Coffee and tea drinking may be associated with reduced rates of stroke and dementia Posted: 16 Nov 2021 11:48 AM PST Drinking coffee or tea may be associated with a lower risk of stroke and dementia, according to a new study. Drinking coffee was also associated with a lower risk of post-stroke dementia. |
| In spreading politics, videos may not be much more persuasive than their text-based counterparts Posted: 16 Nov 2021 10:16 AM PST Video clips are only modestly more persuasive to audiences than the written word is, according to researchers who conducted an experiment about political misinformation. |
| Neuroscientists illuminate how brain cells 'navigate' in the light and dark Posted: 16 Nov 2021 08:14 AM PST Researchers have discovered how individual and networks of cells in an area of the brain called the retrosplenial cortex encode this angular head motion in mice to enable navigation both during the day and at night. |
| Older-looking brains linked to lower birth weight and genes Posted: 16 Nov 2021 08:13 AM PST In brain scans of almost 1500 people throughout Europe, researchers found that people with 'older-looking' brains had both lower birth weight and genes for smaller brains, compared with those with normal aging brains. Both these factors are present early in life, indicating that your 'brain age' is mostly related to early life influences and not so much on events that happen later in life. |
| Medical training takes a mental toll, but less than a decade ago Posted: 15 Nov 2021 06:29 PM PST A 13-year effort to track the mental health of new doctors in their most stressful time of training shows signs that things have gotten better. But those first-year residents, also called interns, still have a sizable risk of developing depression. And many who do still don't seek help. |
| Can we tell someone’s cultural group from the way they laugh? Posted: 15 Nov 2021 01:54 PM PST Can we infer someone's cultural group from their laugher, even when we do not know what they are laughing at? And what kind of laughter do we find most positive? A new study shows that our laughter gives us away. The study included Dutch and Japanese producers of laughter and listeners. Listeners could detect whether a laughing person is from their own or another cultural group by only hearing a brief laughter segment. Spontaneous laughter was rated as most positive by both groups. |
| New approach provides potential vaccine and treatment for Alzheimer’s Posted: 14 Nov 2021 05:17 PM PST A promising new approach to potentially treat Alzheimer's disease -- and also vaccinate against it -- has been developed by a team of scientists. |
