brain activity

NASA is investigating the best methods for monitoring brain activity as part of a study designed to help airplane pilots realize when they are operating under dangerous levels of stress, fatigue and distraction.

Scientists have long known that women's preferences for masculine men change throughout their menstrual cycles. A new study is the first to demonstrate differences in brain activity as women considered masculinized and feminized male faces and whether the person was a potential sexual partner.

(Netherlands Organization for Scientific Research) Scientists from Maastricht University have developed a method to look into the brain of a person and read out who has spoken to him or her and what was said.

With the help of neuroimaging and data mining techniques the researchers mapped the brain activity associated with the recognition of speech sounds and voices.

Neuroscientists have discovered patterns of brain activity that may underlie our remarkable ability to see and understand the three-dimensional structure of objects.

A new study shows that the successful manipulation of sensorimotor rhythm (SMR) amplitude by instrumental SMR conditioning (ISC) improved sleep quality as well as declarative learning.

ISC might thus be considered a promising nonpharmacological treatment for primary insomnia.

Using mathematics and a computer model of brain activity, scientists have shown a direct link between activity in the cortex and the microscopic structure of this neuronal network.

Building on the existing body of research, the new work indicates that the spontaneous activity of small neuronal networks in the cortex consists of highly structured patterns rather than random "noise," shedding light on previous speculations.

Right now, about half of all people who take medicine for an anxiety disorder don't get much help from it. And doctors have no definitive way to predict who will, and who won't, benefit from each antianxiety prescription they write.

But in a recently published study and a new clinical trial, scientists are working to bring more certainty to anxiety treatment, by probing the connection between brain activity, genetics and medication.

Having a lower social standing increases the likelihood that a monkey faced with a stressful situation will choose cocaine over food, according to a new study.

More dominant monkeys undergoing the same stressful situation had fewer changes in brain activity in areas of the brain involved in stress and anxiety and were less likely to choose cocaine.

Emotions play an important role in the lives of humans, and influence our behavior, thoughts, decisions, and interactions.

The ability to regulate emotions is essential to both mental and physical well-being.
