Aug 15th 2024, 18:58

In humans, the process of learning is driven by different groups of cells in the brain firing together. For instance, when the neurons associated with the process of recognizing a dog begin to fire in a coordinated manner in response to the cells that encode the features of a dog -- four legs, fur, a tail, etc. -- a young child will eventually be able to identify dogs going forward. But brain wiring begins before humans are born, before they have experiences or senses like sight to guide this cellular circuitry. How does that happen?

Aug 15th 2024, 16:36

A mathematical framework that builds on the economic theory of hidden-action models provides insight into how the unobservable nature of effort and risk shapes investigators' research strategies and the incentive structures within which they work, according to a new study.

Aug 15th 2024, 16:36

While everyone knows that a good night's sleep restores energy, a new study finds it resets another vital function: memory.

Aug 15th 2024, 16:36

A new study reveals that the memory for a specific experience is stored in multiple parallel 'copies'. These are preserved for varying durations, modified to certain degrees, and sometimes deleted over time.

Aug 15th 2024, 12:42

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

Aug 15th 2024, 12:42

Middle-aged women who experience work-related stress have a significantly increased risk of future sick leave, a new study shows. Lack of influence and conflicts at work are clear stress factors.

Aug 15th 2024, 12:42

Researchers have uncovered a significant genetic connection between Alzheimer's disease (AD) and several coronary artery disease (CAD) related disorders and lipid classes, offering opportunities to improve health outcomes across two of the more common causes of death in Australia.

Aug 15th 2024, 12:41

Scientists have restored the brain's waste-clearing process in aging mice, offering potential new treatment for Alzheimer's and Parkinson's using existing drugs.

Aug 15th 2024, 12:41

A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.

Aug 14th 2024, 18:58

Psychologists studied 'earworms,' the types of songs that get stuck in your head and play automatically on a loop, to show that highly accurate pitch memory is much more common than might be expected.

(https://www.sciencedaily.com/releases/2024/08/240814160730.htm) Do people with high blood pressure have a higher risk of Alzheimer's disease?
Aug 14th 2024, 16:07

People 60 and older with untreated high blood pressure may have an increased risk of Alzheimer's disease compared to both people who have been or are being treated for high blood pressure as well as people without the chronic condition. These results do not prove that untreated high blood pressure causes Alzheimer's disease, they only show an association.

(https://www.sciencedaily.com/releases/2024/08/240814124630.htm) Scientists discover breakthrough method to activate dormant stem cells in the brain
Aug 14th 2024, 12:46

Scientists have discovered a novel pathway to wake up dormant neural stem cells, offering potential new therapies for neurodevelopmental disorders such as autism, learning disabilities, and cerebral palsy.
