Electrical Brain Patterns Predict Stress Response
the MPR take:
How well an individual handles stress may be due to the relationship between two interconnected parts of the brain, suggest researchers from Duke University in a study published in the journal Nature Communications. Mice were implanted with electrodes so that the activity of the prefrontal cortex and amygdala could be analyzed for responses in electrical patterns when subjected to a stressful situation. For mice that were subjected to a chronically stressful situation for approximately two weeks, the degree to which the prefrontal cortex appeared to regulate amygdala activity was linked to the success of coping with the stress. Mice that showed greater activation of their prefrontal cortex-amygdala circuit even before stress exposure were then more sensitive to the chronically stressful situations. This new research could lead to not only potential treatments for stress, but also prevention of mental illnessess linked with stress.
(Duke University) Some people handle stressful situations better than others, and it's not all in their genes: Even identical twins show differences in how they respond to adversity. Researchers have identified an electrical pattern in the brains of genetically identical mice that predicts how well individual animals will fare in stressful situations.
