Nov 6th 2024, 17:19

Older people who are sleepy during the day or lack enthusiasm for activities due to sleep issues may be more likely to develop a syndrome that can lead to dementia, according to a new study.

Nov 6th 2024, 13:23

A new cell type provides a missing piece of the neural network regulating appetite.

Nov 6th 2024, 13:22

By scanning the brains of people while they watched movie clips, neuroscientists have created the most detailed functional map of the brain to date. The fMRI analysis shows how different brain networks light up when participants viewed short clips from a range of independent and Hollywood films including Inception, The Social Network, and Home Alone. The team identified different brain networks involved in processing scenes with people, inanimate objects, action, and dialogue. They also revealed how different executive networks are prioritized during easy- versus hard-to-follow scenes.

Nov 6th 2024, 13:22

A new study changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons that respond to learning events and control memory recall. Neurologists have now expanded this theory by showing that non-neuronal cell types in the brain called astrocytes -- star-shaped cells -- also store memories and work in concert with groups of neurons called engrams to regulate storage and retrieval of memories.

Nov 6th 2024, 13:22

Thin, flexible device could help people with visual impairments 'feel' surroundings. Device comprises a hexagonal array of 19 actuators encapsulated in soft silicone. Device only uses energy when actuators change position, operating for longer periods of time on a single battery charge.

Nov 6th 2024, 13:22

Researchers have discovered a neural mechanism for memory integration that stretches across both time and personal experience.

Nov 6th 2024, 13:21

Neuroscientists have discovered brain cells that form multiple coordinate systems to tell us 'where we are' in a sequence of behaviors. These cells can play out different sequences of actions, just like a music box can be configured to play different sequences of tones. The findings help us understand the algorithms used by the brain to flexibly generate complex behaviors, such as planning and reasoning, and might be useful in understanding how such processes go wrong in psychiatric conditions such as schizophrenia.

Nov 5th 2024, 17:49

A new study of more than 1,000 adults, average age 33, found that meeting recommended physical activity guidelines isn't enough to counteract the 60-plus hours per week they spend sitting. To reduce heart disease risk and prevent accelerated aging, they need to sit less and work-out harder.

Nov 5th 2024, 11:43

By examining RNA in hundreds of thousands of individual brain cells, scientists further support that alcohol use disorder could accelerate Alzheimer's disease progression, paving the way for future targeted treatments.

Nov 4th 2024, 15:05

Children too young to know words like 'impossible' and 'improbable' nonetheless understand how possibility works, finds new work with two- and three-year-olds. The findings demonstrate that young children distinguish between improbable and impossible events, and learn significantly better after 'impossible' occurrences.

Nov 4th 2024, 14:22

Researchers have uncovered new targets that could be the key to effectively treating glioblastoma, a lethal type of brain cancer. These targets were identified through a screen for genetic vulnerabilities in patient-derived cancer stem cells that represent the variability found in tumors.
