Physical pain and intense feelings of social rejection "hurt" in the same way, a new study shows. The study demonstrates that the same regions of the brain that become active in response to painful sensory experiences are activated during intense experiences of social rejection. "These results give new meaning to the idea that social rejection 'hurts'," said University of Michigan social psychologist Ethan Kross, lead author of the article published in the Proceedings of the National Academy...

The Insula and Evaluative Processes Gary G. Berntson, Greg J. Norman, Antoine Bechara, Joel Bruss, Daniel Tranel, and John T. Cacioppo The insula has been implicated in evaluative and affective processes. New findings indicate that the insula may be broadly involved in integrating affective and cognitive processes. Participants rated the positivity and negativity of picture stimuli and how emotionally arousing they found the pictures to be. Volunteers with lesions of the insula exhibited...

(Ivanhoe Newswire)--Not a believer in acupuncture?  Think the pain's all in your head?  Have a personal vendetta against needles?  Alternative health isn't really your thing?  Well, It's time to lay your fears about acupuncture to rest as study results suggest the effectiveness of acupuncture. Using functional magnetic resonance imaging (fMRI), researchers have captured pictures of the brain while patients experienced a pain stimulus with and without acupuncture to...

Using functional magnetic resonance imaging (fMRI), researchers have captured pictures of the brain while patients experienced a pain stimulus with and without acupuncture to determine acupuncture's effect on how the brain processes pain. Results of the study, which the researchers say suggest the effectiveness of acupuncture, were presented today at the annual meeting of the Radiological Society of North America (RSNA). "Until now, the role of acupuncture in the perception and processing of...

New findings released today help identify the long-term impact of the prenatal environment and early parental care on the brain. Using animals as models, researchers help explain why early inflammation and a mother's exposure to drugs such as nicotine and high doses of pain killers have lasting consequences for children "” and even future generations. Maternal drug use has been associated with increased risk for learning disabilities, behavioral problems, and mental disorders for...

A new study reveals that brain signals elicited by the sight of someone suffering pain differ as a function of whether we identify positively or negatively with that person and that these differential brain signals predict a later decision to help or withdraw from helping. The research, published by Cell Press in the October 7th issue of the journal Neuron, provides fascinating insight into the neural mechanisms involved in decisions that benefit others, known as prosocial behavior, and how...

There is new evidence that people can learn to control the activity of some brain regions when they get feedback signals provided by functional magnetic resonance brain imaging (fMRI). Dr. Andrea Caria and colleagues used this specialized imaging technique during training sessions in three groups of healthy participants who were asked to assess visual emotional stimuli (negative or neutral pictures). The scientists were interested in the signals generated by the insula, a brain region...

Researchers using functional magnetic resonance imaging (fMRI) to study brain activation have found that men and women respond differently to positive and negative stimuli, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). "Men may direct more attention to sensory aspects of emotional stimuli and tend to process them in terms of implications for required action, whereas women direct more attention to the feelings engendered by...

Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
