News about our knowledge of the brain and behavior
from Anthony Risser, Ph.D.
During the study, 27 depressed patients and 19 control participants were presented with visual images intended to evoke either a positive or a negative emotional response. While viewing these images, participants were instructed to use cognitive strategies to increase, decrease or maintain their emotional responses to the images by imagining themselves in similar scenarios. Heller and colleagues used functional magnetic resonance imaging (fMRI) to measure brain activity in the target areas. The scientists examined the extent to which activation in the brain's reward centers to positive pictures was sustained over time. The work was funded by grants from the National Institute of Mental Health, Wyeth-Ayerst Pharmaceuticals, Fetzer Institute and Impact Foundation, and by gifts from the John W. Kluge Foundation, Bryant Wangard, Ralph Robinson and Keith and Arlene Bronstein.eeg machine
