More evidence that blood tests can detect the risk of Alzheimer’s

A new study confirms that a simple blood test can reveal whether there is accelerating nerve cell damage in the brain. The researchers analyzed neurofilament light protein (NFL) in blood samples from patients with Alzheimer’s disease. The study suggest…

Stressed, anxious? Ask the brain!

Our actions are driven by ‘internal states’ such as anxiety, stress or thirst — which will strongly affect and motivate our behaviors. Little is known about how such states are represented by complex brain-wide circuits, including sub-cortical structu…

A new window into macaque brain connections

Researchers can now see how the two sides of the living brain mirror each other thanks to a new combination-imaging technique. The method dubbed ‘opto-OISI’ takes advantage of rapidly developing high-resolution optical technologies to help make sense o…

Brains of blind people adapt to sharpen sense of hearing, study shows

Research uses functional MRI to identify two differences in the brains of blind individuals — differences that might be responsible for their abilities to make better use of auditory information.

Sugar entering the brain during septic shock causes memory loss

The loss of memory and cognitive function known to afflict survivors of septic shock is the result of a sugar that is released into the blood stream and enters the brain during the life-threatening condition.

Neuroscientists reverse some behavioral symptoms of Williams syndrome

In a study of mice, neuroscientists have found that impaired myelination underlies the hypersociability seen in patients with Williams syndrome.

New insight into how obesity, insulin resistance can impair cognition

Obesity can break down our protective blood brain barrier resulting in problems with learning and memory, scientists report.

Light, physical activity reduces brain aging

Incremental physical activity, even at light intensity, is associated with larger brain volume and healthy brain aging, according to new research.

Important insight on the brain-body connection

A study reveals that neurons in the motor cortex exhibit an unexpected division of labor, a finding that could help scientists understand how the brain controls the body and provide insight on certain neurological disorders.

Brain wiring differences identified in children with conduct disorder

Behavioral problems in young people with severe antisocial behavior — known as conduct disorder — could be caused by differences in the brain’s wiring that link the brain’s emotional centers together, according to new research.
