Brain waves measure the effect of anti-alcohol campaigns

To evaluate the effectiveness of public video campaigns against risky alcohol consumption, psychologists used EEG measurements to examine the synchronization of brain activity in groups of viewers. In a recent study, they present new ways to bring the …

Electroencephalography may help guide treatments for language disorders

Electroencephalography (EEG) may offer a more accessible alternative to functional magnetic resonance imaging (fMRI) for guiding transcranial direct current stimulation (tDCS) when treating aphasia. Researchers found an 80% agreement between EEG and fM…

Scientists discover brain mechanism that helps us overcome fear

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 stres…

Improved brain decoder holds promise for communication in people with aphasia

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 comm…

Air pollution clouds the mind and makes everyday tasks challenging

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.

The two proteins involved in Alzheimer’s disease affect brain circuits differently

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 an…

Research in fruit flies pinpoints brain pathways involved in alcohol-induced insomnia

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 …

Scientists reveal gut microbes’ hidden role in anxiety: Could probiotics be the next mental health breakthrough?

Could the key to easing anxiety be hidden in our gut? Scientists have discovered a crucial connection between gut microbes and anxiety-related behavior. Their research suggests that microbial metabolites — specifically indoles — play a direct role in…

Study finds new link between food choices, depression and Alzheimer’s Disease

New research has shown that diet could influence the risk of both depression and Alzheimer’s disease (AD). Evidence suggests that depressive symptoms are both a risk factor for AD and a reaction to early memory problems.

Mouth bacteria may hold insight into your future brain function

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.
