Oops! Researchers publish new findings on the brain's response to costly mistakes

...RP to study brain responses to various situations, assessing changes in electrical activity through sensors arranged on a mesh cap that is placed on the head. The method is similar to techniques used to study the brains of people with epilepsy or sleep problems, but the electrical signal from the brain is proc...

U of MN researchers develop way to visualize synchronized interactions of nerve cells in the brain

...isease, and to monitor the effect of treatment, by assessing the status of the brain networks over time," Georgopoulos said. All behavior and cognition in the brain involves networks of nerves continuously interacting--these interactions occur on a millisecond by millisecond basis. Because the interactions ...

Researchers test new way to quit smoking

... is regarded as a critical make-or-break date when assessing quitting success." Findings from the research will provide useful information about more effective use of nicotine patches and gum for people who want to quit smoking, estimated to number about 430,000 people in New Zealand alone. There are several...

New book on rain forests, slash-and-burn agriculture

"Being able to accurately measure this number is often important in obesity research and understanding eating disorders. The greater the metabolic activity of a cell, the bigger the difference between the 'inside' wate...

Many smokers fail to quit after cancer diagnosis

... and pharmacotherapy, but only a few studies exist assessing their efficacy. Another shortfall is that these studies, with one exception, target smokers with smoking-related cancers. The common finding was that the healthcare provider has a significant impact on smoking cessation rates. Interventions may have ...
