Neuroscientists trying to tease out the mechanisms underlying the basis of human sympathy have found that such feelings trigger brain activity not only in areas associated with emotion but also in areas associated with performing an action. But, when people act in socially inappropriate ways this activity is replaced by increased activity in regions associated with social conflict.
Understanding the neurophysiology of such basic human characteristics as sympathy is important because some people lack those feelings and may behave in anti-social ways that can be extremely costly to society, said Dr. Jean Decety of the University of Washington. Decety heads the social-cognitive neuroscience laboratory at the UWs Center for Mind, Brain & Learning and is lead author of a new study that appears in a just-published special issue of the journal Neuropsychologia.
In the study, Decety and doctoral student Thierry Chaminade used positron emission tomography (PET) scans to explore what brain systems were activated while people watched videos of actors telling stories that were either sad or neutral in tone. The neutral stories were based on everyday activities such as cooking and shopping. The sad stories described events that could have happened to anyone, such as a drowning accident or the illness of a close relative. The actors were videotaped telling the stories, which lasted one to two minutes, with three different expressions – neutral, happy or sad.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.
Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
