Neuroplasticity and aging: your brain can still change
Neuroplasticity and aging show the brain can still change in adult life. Practice, challenge, and attention help, but plasticity is not magic.
Plant pigment phytoene helps worms live longer and eases Alzheimer’s-like damage
Researchers report that phytoene, a natural carotenoid pigment found in many fruits and vegetables, helped laboratory worms live longer and show fewer signs linked to Alzheimer’s disease. In tests with the model animal Caenorhabditis elegans, phytoene lengthened lifespan and delayed…
Positive memory reactivation during sleep reduces negative memory recall
Reactivating positive memories during non-REM sleep can weaken the recall of associated negative memories. This sleep-based technique, known as targeted memory reactivation (TMR), involves presenting auditory cues linked to positive experiences during sleep, leading to a reduction in negative memory…
Being open to new things helps creativity and learning, and may keep the brain healthier with age
Openness is a personality trait that means seeking and enjoying new and unfamiliar things. Research in psychology and neuroscience links greater openness with benefits for thinking and mood. People who are more open tend to explore more, learn faster, and…
The brain reorganizes itself after 40 to optimize cognitive function
After age 40, the brain undergoes significant reorganization, integrating its networks more extensively. This shift aims to optimize function with diminishing resources and aging structures. While this “rewiring” can affect executive functions like flexible thinking and abstract reasoning, tasks reliant…
videoHow strong your muscles are may be the single best marker of overall health
Video (in French) According to Professor Martine Duclos, endocrinologist. Muscle strength is a good marker of a person’s health, particularly their risk of mortality or developing cardiovascular diseases. In the study cited, individuals with the lowest muscle strength had: Muscle…
Why some people are always late and what it reveals about them
To be five minutes late is not really to be late. Late is when people start getting annoyed. Being eight minutes late is not perceived as being late, and gives your host just enough time to sit down for a…
Night owls may be smarter than early risers
Les couche-tard seraient plus intelligents que les couche-tôt, mais une durée de sommeil de 7h à 9h est plus importante.
