How the ear can inform the brain of whether hearing is impaired

A cochlear signal, the exact role of which has been unclear since its discovery around 70 years ago, probably gives the brain information on whether the ear is functioning normally or not. These new findings are an important piece of the puzzle in expl…

Brain scans reveal that lonely people process the world in unique ways

Loneliness is detrimental to well-being and often accompanied by feelings of not being understood by others. A new study found that the brain responses of lonely people differ from those of other lonely people and from those of people who are not lonel…

Brain imaging-based biomarker of depression identified

Major depressive disorder (MDD) is not only among the most common mental illnesses, affecting over 8% of Americans, but it is also extremely variable from one person to another. Researchers have recently begun making strides toward understanding the ne…

How the brain processes numbers — New procedure improves measurement of human brain activity

Measuring human brain activity down to the cellular level: until now, this has been possible only to a limited extent. With a new approach it will now be much easier. The method relies on microelectrodes along with the support of brain tumor patients, …

Neural signature for borderline personality disorder identified

A new study of a brain region called the rostro-medial prefrontal could potentially advance diagnosis and therapies for Borderline Personality Disorder (BPD).

Reading for pleasure early in childhood linked to better cognitive performance and mental wellbeing in adolescence

Children who begin reading for pleasure early in life tend to perform better at cognitive tests and have better mental health when they enter adolescence, a study of more than 10,000 young adolescents in the US has found.

Chemical imbalance in the forebrain discovered in people with obsessive-compulsive disorder

Scientists have discovered an imbalance between neurochemicals in parts of OCD patients’ brains key to decision-making and habit. A similar but less pronounced neurochemical imbalance was also detected in healthy individuals with milder compulsive tend…

Poverty negatively impacts structural wiring in children’s brains, study indicates

A study reveals that household and community poverty may influence brain health in children. Childhood obesity and lower cognitive function may explain, at least partially, poverty’s influence on the brain.

Molecular imaging identifies brain changes in response to food cues; offers insight into obesity interventions

Molecular imaging with 18F-flubatine PET/MRI has shown that neuroreceptors in the brains of individuals with obesity respond differently to food cues than those in normal-weight individuals, making the neuroreceptors a prime target for obesity treatmen…

Poor sense of smell linked to increased risk of depression in older adults

In a study that followed more than 2,000 community-dwelling older adults over eight years, researchers say they have significant new evidence of a link between decreased sense of smell and risk of developing late-life depression.
