People who care about justice are swayed more by reason than emotion, according to new brain scan research from the Department of Psychology and Center for Cognitive and Social Neuroscience.
Psychologists have found that some individuals react more strongly than others to situations that invoke a sense of justice—for example, seeing a person being treated unfairly or mercifully. The new study used brain scans to analyze the thought processes of people with high “justice sensitivity.” (more…)
People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty.
There are many different sources of beauty – a beautiful face, a picturesque landscape, a great symphony are all examples of beauty derived from sensory experiences. But there are other, highly intellectual sources of beauty. Mathematicians often describe mathematical formulae in emotive terms and the experience of mathematical beauty has often been compared by them to the experience of beauty derived from the greatest art.

A region deep inside the brain controls how quickly people make decisions about love, according to new research at the University of Chicago.
The finding, made in an examination of a 48-year-old man who suffered a stroke, provides the first causal clinical evidence that an area of the brain called the anterior insula “plays an instrumental role in love,” said UChicago neuroscientist Stephanie Cacioppo, lead author of the study. (more…)
Research by the Universities of Liverpool and Manchester has found that people experiencing depressive episodes display increased brain activity when they think about themselves.
Using functional magnetic resonance imaging (fMRI) brain imaging technologies, scientists found that people experiencing a depressive episode process information about themselves in the brain differently to people who are not depressed.
Researchers scanned the brains of people in major depressive episodes and those that weren’t whilst they chose positive, negative and neutral adjectives to describe either themselves or the British Queen – a figure significantly removed from their daily lives but one that all participants were familiar with.

UCLA psychologists have used brain-imaging techniques to study what happens to the human brain when it slips into unconsciousness. Their research, published Oct. 17 in the online journal PLOS Computational Biology, is an initial step toward developing a scientific definition of consciousness.
“In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving from Los Angeles to New York in a straight line versus having to cover the same route hopping on and off several buses that force you to take a ‘zig-zag’ route and stop in several places,” said lead study author Martin Monti, an assistant professor of psychology and neurosurgery at UCLA.

Scientists use new methods developed by UCLA’s Martin Monti
A team of American and Israeli brain scientists tested former Israeli Prime Minister Ariel Sharon to assess his brain responses, using functional magnetic resonance imaging (fMRI). Surprisingly, Sharon showed significant brain activity.
The team consisted of Martin Monti, an assistant professor of psychology and neurosurgery at UCLA, professors Alon Friedman, Galia Avidan and Tzvi Ganel of the Zlotowski Center for Neuroscience at Israel’s Ben-Gurion University of the Negev, and Dr. Ilan Shelef, head of medical imaging at Israel’s Soroka University Medical Center.

Training human volunteers to control their own brain activity in precise areas of the brain can enhance fundamental aspects of their visual sensitivity, according to a new study in the Journal of Neuroscience.
This non-invasive ‘neurofeedback’approach could one day be used to improve brain function in patients with abnormal patterns of activity, for example stroke patients. (more…)
Brain shows diminished response to untrustworthiness, UCLA scientists report
Why are older people especially vulnerable to becoming victims of fraud? A new UCLA study indicates that an important clue may lie in a particular region of the brain that influences the ability to discern who is honest and who is trying to deceive us.
Older people, more than younger adults, may fail to interpret an untrustworthy face as potentially dishonest, the study shows. The reason for this, the UCLA life scientists found, seems to be that a brain region called the anterior insula, which is linked to disgust and is important for discerning untrustworthy faces, is less active in older adults.
