The stress response is associated with brain activity in the amygdala and the prefrontal cortex. The amygdala initiates the fight, flight, or freeze response to fear-inducing stimuli, while the prefrontal cortex helps modulate this response. A higher degree of connectivity between these brain regions is thought to enhance emotional regulation. These conclusions are based on research with adults. Little is known about the neural basis for children’s responses to stress, however, and whether it can be beneficially modified by mindfulness-based interventions.
Bauer et al. [Behavioral Neuroscience] tested whether mindfulness training reduces stress levels in middle school children, and if so, whether it is done by inducing changes in the amygdala and its connectivity to a region of the prefrontal cortex. This is the first study investigating the effects of a mindfulness-based intervention on children’s brain activity.
All 6th graders in a Boston charter school were randomly assigned to an 8-week mindfulness training program or an 8-week computer coding training program. The researchers requested the 6th graders’ families to permit their children to participate in the functional magnetic imaging (fMRI) portion of the study. Forty children received permission (average age = 12 years; 70% female; 53% Caucasian; Average WASI IQ = 98), and 33 of their fMRI protocols were usable.
Mindfulness and computer coding groups met four times a week for 45 minutes during the last class of the school day. Each mindfulness session included 15 minutes of mindfulness exercises involving focused attention on the present moment and related didactic instruction and group discussion. Exercises included focused breath meditations, attention to the senses, open monitoring, and practice in noticing thoughts.
