Personal reflection triggers increased brain activity during depressive episode

12 Nov 2013 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. Professor Peter Kinderman, Head of the University's Institute of Psychology, Health and Society, said: "We found that participants who were experiencing depressed mood chose significantly fewer positive words and more negative and neutral words to describe themselves, in comparison to participants who were not depressed. "That's not too surprising, but the brain scans also revealed significantly greater blood oxygen levels in the medial superior frontal cortex - the area associated with processing self-related information - when the depressed participants were making judgments about themselves. "This research leads the way for further studies into the psychological and neural processes that accompany depressed mood. Understanding more about how people evaluate themselves when they are depressed, and how neural processes are involved could lead to improved understanding and care.
