- Memory helps us evaluate situations on the fly, not just recall the pastam 18. Juni 2021 um 19:35
Scientists have long known the brain's hippocampus is crucial for long-term memory. Now a new study has found the hippocampus also plays a role in short-term memory and helps guide decision-making. The findings shed light on how the hippocampus contributes to memory and exploration, potentially leading to therapies that restore hippocampal function, which is impacted in memory-related aging and neurodegenerative diseases such as dementia, the study authors said.
- In the visual thalamus, neurons are in contact with both eyes but respond to only oneam 18. Juni 2021 um 17:41
The visual thalamus is classically known to relay visual stimuli coming from the retina to the cerebral cortex. Researchers now show that although neurons in the mouse visual thalamus connect to both eyes, they establish strong functional connections only with one retina. These results settle partly contradictory results of earlier studies and demonstrate how important it can be to complement structural data with functional analyses.
- How childhood exercise could maintain and promote cognitive function in later lifeam 18. Juni 2021 um 17:40
People who are physically active during childhood have higher cognitive functions in later life. Participants who exercised when they were children did better on cognitive tests regardless of their current age. However, no such relationship was found between task performance and post-childhood exercise -- suggesting that exercise during childhood is particularly important for brain development and long-term cognitive health.
- Researchers find losartan is not effective in reducing hospitalization from mild COVID-19am 18. Juni 2021 um 17:40
In a new study, researchers determined that the common blood pressure medication, losartan, is not effective in reducing hospitalization for mildly-ill COVID-19 outpatients.
