Scientists at the Naval Research Laboratory (NRL) in conjunction with the Scripps Research Institute in La Jolla, Ca., recently reported a detailed study of the interactions of water soluble semi-conductor quantum dots (QDs) with the electro-active neuro-transmitter dopamine. These biocompatible QD-dopamine nano-assemblies may be used as the active component for sensors that are used to detect a wide variety of target analytes ranging from sugars to peroxides. According to NRL's Dr. Michael...

New animal research demonstrates diet-induced changes in brain chemical release Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that prolonged exposure to a high fat diet is correlated with changes in the brain chemical dopamine within the striatum, a critical component of the brain's reward system.  The authors measured...

Brain study highlights role of dopamine in impulsive behavior It's a common scenario: you're on a diet, determined to give up eating cakes, but as you pass the cake counter, all resolve disappears"¦ Now, scientists at the Wellcome Trust Centre for Neuroimaging at UCL (University College London) have shed light on the brain processes that affect our will power and make us act impulsively. In a study published today in the Journal of Neuroscience, funded mainly by the Wellcome Trust,...

We've all experienced the strong heartbeat that accompanies emotions such as fear and rage. But can the body's natural response to these emotions be used to combat heart failure? Results of a study published online today in the journal Circulation Research present a strong case. In the study, scientists from the University of Rochester Medical Center found that two experimental drugs have the potential to restore pumping strength to failing hearts in part by harnessing the fight-or-flight...

There are biological motivations behind the stereotypically poor decisions and risky behavior associated with adolescence, new research from a University of Texas at Austin psychologist reveals. Previous studies have found that teenagers tend to be more sensitive to rewards than either children or adults. Now, Russell Poldrack and fellow researchers have taken the first major step in identifying which brain systems cause adolescents to have these urges and what implications these biological...

New research shows a possible explanation for the link between mental health and creativity. By studying receptors in the brain, researchers at Karolinska Institutet have managed to show that the dopamine system in healthy, highly creative people is similar in some respects to that seen in people with schizophrenia. High creative skills have been shown to be somewhat more common in people who have mental illness in the family. Creativity is also linked to a slightly higher risk of...

Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have developed an imaging protocol that allows them to visualize the activity of the brain's reward circuitry in both normal individuals and those addicted to drugs. The technique could lead to better insight into why people take recreational drugs as well as help determine which treatment strategies might be most effective. Drug addiction is a complex process that involves numerous biological and environmental...

Brain scans show persistent motivation regardless of payoff Whether it's for money, marbles or chalk, the brains of reward-driven people keep their game faces on, helping them win at every step of the way. Surprisingly, they win most often when there is no reward. That's the finding of neuroscientists at Washington University in St. Louis, who tested 31 randomly selected subjects with word games, some of which had monetary rewards of either 25 or 75 cents per correct answer, others of which...

Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
