Removal of ovaries before menopause associated with reduced white matter in brain

Women who have their ovaries removed before menopause, particularly before the age of 40, have reduced white matter integrity in multiple regions of the brain later in life, a new study suggests. White matter refers to the nerve fibers that connect neu…

Shining light on mental health in space science community

The severity of anxiety and depressive symptoms in the planetary science community is greater than in the general U.S. population, according to a new study.

‘Time cells’ in the brain are critical for complex learning, study shows

They’re more than a simple clock, and understanding these cells’ activity could ultimately aid in early detection of neurodegenerative diseases.

New technology allows researchers to precisely, flexibly modulate brain

Researchers have developed a noninvasive technology combining a holographic acoustic device with genetic engineering that allows them to precisely target affected neurons in the brain, creating the potential to precisely modulate selected cell types in…

New study reveals urgent need for region-specific models to improve brain health in diverse settings

A pioneering study has unveiled significant heterogeneity in the risk factors affecting healthy aging in Latin America and emphasized the limitations of current models of brain health, which are primarily based on data from high-income countries.

A high-fat diet may fuel anxiety

New research shows when animals are fed a diet high in saturated fat for nine weeks, their gut bacteria change in ways that influence brain chemicals and fuel anxiety.

Breakthrough approach enables bidirectional BCI functionality

Brain-computer interfaces or BCIs hold immense potential for individuals with a wide range of neurological conditions, but the road to implementation is long and nuanced for both the invasive and noninvasive versions of the technology. Scientists have …

A new approach to neuroimaging analysis

A new method for neuroimaging analysis is shown to work with small groups of participants, opening the door for many studies that don’t have access to massive sets of brain images.

New metric for blood circulation in brain to better understand dementia

Researchers have developed a new metric from measured blood circulation in our brain. This metric has implications for brain conditions, including Alzheimer’s disease and other forms of dementia.

New insights into the brain regions involved in paranoia

The capacity to adjust beliefs about one’s actions and their consequences in a constantly changing environment is a defining characteristic of advanced cognition. Disruptions to this ability, however, can negatively affect cognition and behavior, leadi…
