Richard J. Davidson, a neuroscientist at the University of Wisconsin, has been looking at patterns of brain activity associated with emotional regulation in a small group of older people who have participated in the Wisconsin Longitudinal Study. In a paper published last year, the Wisconsin team reported that older adults (the average age was 64) who regulated their emotions well showed a distinctly different pattern of brain activity than those who didnâ??t. These people apparently used their prefrontal cortex, the part of the brain that exerts â??executive controlâ? over certain brain functions, to tamp down activity in the amygdala, a small region deep in the brain that processes emotional content, especially fear and anxiety. In people who are poor regulators of emotion, activity in the amygdala is higher, and daily measurements of the stress hormone cortisol follow a pattern that has been associated with poor health outcomes.
