Neurobiology of Stress

Therapeutic interventions that incorporate training in mindfulness meditation have become increasingly popular, but to date, little is known about neural mechanisms associated with these interventions. Mindfulness-Based Stress Reduction (MBSR), one of the most widely used mindfulness training programs, has been reported to produce positive effects on psychological well-being and to ameliorate symptoms of a number of disorders. Here, we report a controlled longitudinal study to investi […]

Evaluated self-esteem and locus of control in a group of high school students prior to, during, and following a single academic year. Using a randomized, crossover experimental design, 26 Ss were exposed to either a health curriculum based on elicitation of the relaxation response (RLR) and then a follow-up period, while 24 were assigned to a control health curriculum and then the RLR. Psychological testing was conducted using the Piers-Harris Children's Self Concept Scale and the Now […]

Previous research indicates that long-term meditation practice is associated with altered resting electroencephalogram patterns, suggestive of long lasting changes in brain activity. We hypothesized that meditation practice might also be associated with changes in the brain's physical structure. Magnetic resonance imaging was used to assess cortical thickness in 20 participants with extensive Insight meditation experience, which involves focused attention to internal experiences. Brai […]
