New experiences enhance learning by resetting key brain circuit Posted: 24 Feb 2021 09:03 AM PST A study of spatial learning in mice shows that exposure to new experiences dampens established representations in the brain's hippocampus and prefrontal cortex, allowing the mice to learn new navigation strategies. |
Reactivating aging stem cells in the brain Posted: 24 Feb 2021 08:30 AM PST As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers have now discovered a mechanism linked to stem cell aging - and how the production of neurons can be reactivated. |
Posted: 24 Feb 2021 07:09 AM PST In the process of developing language, the melody patterns that emerge in infants' vocalizations are a very important first step. A new study has shown that the complexity of these patterns rapidly increases in the first months. |
Changes in writing style provide clues to group identity Posted: 24 Feb 2021 06:06 AM PST Small changes to people's writing style can reveal which social group they 'belong to' at a given moment, new research shows. |
Basic cell health systems wear down in Huntington's disease, novel analysis shows Posted: 23 Feb 2021 08:04 AM PST A new computational approach for analyzing complex datasets shows that as disease progresses, neurons and astrocytes lose the ability to maintain homeostasis. The 'Geomic' approach can be applied to other diseases, authors say. |
Empathy helps explain how parental support can prevent teen delinquency Posted: 22 Feb 2021 04:28 PM PST A new study of nearly 4,000 school children has found that youngsters who feel they have empathic support from their parents and caregivers are verging away from a wide range of delinquent behavior, such as committing crimes. |
New therapeutic approach may help treat age-related macular degeneration effectively Posted: 22 Feb 2021 09:46 AM PST Runt-related transcription factor 1 (RUNX1) has been linked to retinal neovascularization and the development of abnormal blood vessels, which result in vision loss in diabetic retinopathy. Now, scientists have found that RUNX1 inhibition presents a new therapeutic approach in the treatment of age-related macular degeneration (AMD), which is the leading cause of blindness in the elderly worldwide. |
