Feb 6th 2025, 14:24

Researchers have unveiled the precise brain mechanisms that enable animals to overcome instinctive fears. The study in mice could have implications for developing therapeutics for fear-related disorders such as phobias, anxiety and post-traumatic stress disorder (PTSD).

Feb 6th 2025, 13:46

A new AI-based tool can translate a person's thoughts into continuous text, without requiring the person to comprehend spoken words. This latest advance suggests it may be possible, with further refinement, for brain computer interfaces to improve communication in people with aphasia.

Feb 6th 2025, 11:35

People's ability to interpret emotions or focus on performing a task is reduced by short-term exposure to particulate matter (PM) air pollution, potentially making everyday activities, such as the weekly supermarket shop, more challenging.

Feb 6th 2025, 11:35

A research team has discovered that the two key pathological hallmarks of Alzheimer's -- tau protein and beta-amyloid -- affect brain circuits in distinct yet synergistic ways, particularly those linked to memory and emotions. The study, using a new animal model of Alzheimer's disease, suggests a potential breakthrough in treatment strategies. Current therapies mainly focus on blocking just one of the toxic proteins associated with the disease, but this discovery could pave the way for more comprehensive approaches.

Feb 6th 2025, 11:31

Research in fruit flies has identified specific groups of cholinergic brain cells that are involved in alcohol-induced insomnia. This work could ultimately lead to targeted treatments for alcohol-related sleep loss, helping people recover from alcohol use disorder.

Feb 5th 2025, 13:15

A new study has found that certain bacteria were associated with better memory and attention, while others were linked to an increased risk of Alzheimer's disease.

Jan 28th 2025, 12:36

A new study explores the effects of both recent and lifetime cannabis use on brain function during cognitive tasks. The study, the largest of its kind ever to be completed, examined the effects of cannabis use on over 1,000 young adults aged 22 to 36 using brain imaging technology. The researchers found that 63% of heavy lifetime cannabis users exhibited reduced brain activity during a working memory task, while 68% of recent users also demonstrated a similar impact. This decline in brain activity was associated with worse performance on working memory -- the ability to retain and use information to perform tasks. For example, working memory allows a person to follow instructions they've just been given or to mentally visualize and manipulate information, like solving a math problem.
