How ketamine can change the brain to fight depression

New research in mice pinpoints some of the key mechanisms that ketamine triggers in the brain to fight the symptoms and characteristics of depression.

Obesity linked with differences in form and structure of the brain

Researchers using sophisticated MRI technology have found that higher levels of body fat are associated with differences in the brain’s form and structure, including smaller volumes of gray matter, according to a new study. The findings add important i…

Hidden control architecture of brain networks unveiled

Researchers have identified the intrinsic control architecture of brain networks. The control properties will contribute to providing a fundamental basis for the exogenous control of brain networks and, therefore, has broad implications in cognitive an…

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.
