Stimulating brain with ultrasound can influence decisions

Stimulating brain with ultrasound can influence decisions

A noninvasive, low-intensity ultrasound method that targets nerve cells, or neurons, can alter brain function to influence decision-making. New research shows how a brain area called the anterior cingulate cortex controls a type of reasoning known as counterfactual thinking. Scientists have demonstrated the technique in a recent study, in which they disrupted “counterfactual thinking” in […]

Could ‘mirror neurons’ explain brain mechanisms of empathy?

Could ‘mirror neurons’ explain brain mechanisms of empathy?

Scientists have pinpointed a group of cells in the brain whose activity could help explain the ability to share another’s pain. Why can we feel other people’s pain? A recent study in rats investigates. From imaging studies of human brains, it was already clear that a region called the anterior cingulate cortex (ACC), which is […]

Syncing brain waves may fight age-related memory problems

Syncing brain waves may fight age-related memory problems

Memory can deteriorate naturally, due to age, and even when this process is not related to neurodegenerative conditions, such as Alzheimer’s, it can still affect a person’s quality of life. Now, researchers from Boston University in Massachusetts are exploring ways of fighting age-related memory decline. By resynchronizing brain waves, we could reverse some age-related memory […]

How use of digital devices may influence obesity risk

How use of digital devices may influence obesity risk

Recent evidence suggests that people who multitask by switching frequently between digital devices may be more at risk of developing unhealthful eating habits and obesity. Media multitasking may impact obesity risk and eating habits. The more gadgets that become available to us, the more we may feel tempted to explore these new technologies, but their […]

Scientists locate brain circuit that curbs overeating

Scientists locate brain circuit that curbs overeating

The brain has complex circuitry that locks appetite to memories of finding and enjoying food. This drives the feeding behaviors necessary for survival. New research reveals that the circuits include one mechanism that does the opposite: curbing the compulsion to eat in response to food. ‘People may be able to learn to change their relationship […]

Music may enhance the effect of pain relievers

Music may enhance the effect of pain relievers

Bob Marley once said, “One good thing about music, when it hits you, you feel no pain.” A recent study using a mouse model backs up Marley’s musing with some scientific data. Listening to Mozart might boost pain medication. In the past, scientists have explored the idea of using music as a therapy in a […]

This drug failed to treat cancer, but it could improve dementia

This drug failed to treat cancer, but it could improve dementia

Dementia — an umbrella term for various neurodegenerative conditions involving memory loss and other forms of cognitive impairment — is hard to treat because its causes remain unknown. Researchers, however, are making painstaking progress. A new approach to dementia research may bring us closer to a treatment, but unexpected challenges could halt this progress. Dr. […]
