Meet NOTCH2NL, the human-specific genes that may have given us our big brains

The genetic changes behind the expansion of human brains that played an important role in our ability as a species to think, problem-solve, and develop culture have been elusive. But in a pair of papers publishing May 31 in Cell, two teams of researche…

Mothers with high emotional, cognitive control help their children behave

A new parenting study finds that the greater emotional control and problem-solving abilities a mother has, the less likely her children will develop behavioral problems, such as throwing tantrums or fighting.

Cocaine use alters gene expression in brain reward circuits

A study has identified unique genetic changes in the brain’s reward circuitry that are associated with cocaine use, including first-time use, withdrawal, and re-exposure to the drug after prolonged withdrawal. The findings reveal important information …

Social ties could preserve memory, slow brain aging

A strong social network could be the key to preserving memory. New research has found that mice housed in groups had better memories and healthier brains than animals that lived in pairs.

Is there a link between bipolar and narcissism?

Bipolar disorders are mood disorders characterized by extreme high and low moods. Sometimes, a person experiencing a manic episode can be mistaken for having narcissistic traits. Learn more about the link between narcissism, narcissistic personality di…

No more sweet tooth? Scientists switch off pleasure from food in brains of mice

New research in mice has revealed that the brain’s underlying desire for sweet, and its distaste for bitter, can be erased by manipulating neurons in the amygdala, the emotion center of the brain. The research points to new strategies for understanding…

How to build a brain: Discovery answers evolutionary mystery

Researchers have discovered a fundamental process by which brains are built, which may have profound implications for understanding neurodevelopmental conditions like autism and epilepsy. The study also answers an evolutionary mystery about how the del…

Growth hormone may provide new hope for stroke survivors

Less fatigue and better recovery of cognitive abilities such as learning and memory. These may be the results of growth hormone treatment after a stroke, an experimental study of mice suggests.

Prediction method for epileptic seizures developed

Engineers have developed a machine-learning and AI-powered algorithm to predict the onset of epileptic seizures.

Can these hormones provide the key to autism, schizophrenia?

The hormones oxytocin and vasopressin have been linked to pair-bonding, but can they help to improve impaired social behavior? A new study investigates.
