Brain reveals the risk for developing obesity

Obesity risk factors of family background are associated with changes in the brain function, finds a new study. The results show that the function of neural networks regulating satiety and appetite is altered already before a person develops obesity.

Our brains may think two steps ahead when trying to sway others

In an effort to understand how a sense of control over others may influence the brain’s decision-making processes, researchers have tested the ability of healthy human subjects to play a bargaining game. For the first time, they found that people used …

Deep brain stimulation surgery for treatment-resistant depression: Brain rhythm changes fast

Findings provide a putative physiological biomarker of brain state changes that can predict early antidepressant effects.

Abnormal brain changes over time with bipolar disorder

Bipolar disorder (BD) is a debilitating psychiatric disorder characterized by fluctuating periods of depression and mania. Researchers have long suspected that BD may be accompanied by abnormal structural and functional changes in the brain. Small cros…

Recognizing familiar faces relies on a neural code shared across brains

The ability to recognize familiar faces is fundamental to social interaction. This process provides visual information and activates social and personal knowledge about a person who is familiar. But how the brain processes this information across parti…

Researchers boost human mental function with brain stimulation

Researchers show it is possible to improve specific human brain functions related to self-control and mental flexibility by merging artificial intelligence with targeted electrical brain stimulation.

New test to diagnose aggressive childhood brain tumors

Researchers have developed a new test to more easily diagnose medulloblastoma, the most common malignant childhood brain tumor. The test — which can distinguish between extremely high-risk medulloblastoma cases that need radiation therapy from those t…

Dopamine’s many roles, explained

Studying fruit flies, researchers ask how a single brain chemical can orchestrate diverse functions such as learning, motivation and movement.

Cause of Alzheimer’s progression in the brain

For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implicatio…

Brain monitoring suggests common link between electrical tremors and mental health disorders

A new review of current literature has found that irregular responses in the brain to challenging tasks and mistakes could be key to understanding common links between abnormal behaviors in a range of mental illness and cognitive disorders.
