Magnetic Resonance Imaging (MRI) allows us to visualize and measure deep, primitive brain regions involved in desire and emotion. Source: PBS graphic based on Galvan et al 2006, Hare et al 2008, Sackler Institute
Individual differences in brain activity (High Anxiety vs Low Anxiety) SOURCE: Hare et al 2008 Sackler Institute
And during brain development from childhood to adulthood SOURCE: Gogtay et al 2004 PNAS, NIMH
and in Social and Psychological Contexts SOURCE: National Geographic: A Beautiful Brain based on Casey et al Neuron 2010
Key Areas 1) Development. Age-specific changes in regional brain development can impact behavioral choices. 2)Contexts. Emotionally charged contexts may lead to emotional brain regions “hijacking” prefrontal control circuitry leading to poor behavioral choices. 3)Individuals. Variation across individuals (impulsivity, sensation seeking, emotional reactivity) impacts choice behavior.
MRI Data shows Cortical Development across Childhood SOURCE: Gogtayet al 2004 PNAS
Focus has typically been on prefrontal cortex (PFC) Dramatic developmental changes in prefrontal and subcortical regions during adolescence Subcortical limbic regions involved in desire, fight, flight SOURCE: Sowell et al 1999 Nature Neuroscience
Neurobiological (Imbalance) Model of Adolescence Emphasizes deep structure development as well as cortical. SOURCE: Casey et al., 2008 Dev Reviews; Somerville & Casey, 2010 Brain & Cogn.
How does Regional Brain Development map onto Behavioral Development • Hallmark of behavioral development is a gain in ability to suppress an inappropriate action in favor of an appropriate one (impulse control). • Individual Differences • Influence of Context
Development of impulse control(Commission Errors- Go when should Not) SOURCE: Somerville et al. 2010 JoCN
Prefrontal Activity shows Linear pattern of development that is correlated with measures of impulse control SOURCE: Somerville et al 2010 JoCN
Incentives (e.g., money, food, peers) can alter behavior without conscious awareness SOURCE: Galvan et al 2005 J Neuroscience
Teens make more commission errors to rewarding cues than neutral ones Source: Somerville et al 2010 JoCN

Teens show enhanced activity in ventral striatum to positive social cues (e.g., happy faces) Source: Somerville et al 2010 JoCN
Emotional Bias on Choice Behavior Source: Hare et al. 2005 Bio Psychiatry
Inverse association of subcortical limbic and ventromedial prefrontal activity with behavior bias Hare et al 2008 Bio Psychiatry
Inflection in amygdala activity in adolescents to cues that signal threat Source: Hare et al. 2008 Bio Psychiatry
Amygdala Activity to Repeated Exposures of Fear related cues( i.e., empty threat) Early Trials Late Trials Hare et al. 2008 Bio Psychiatry
Habituation of Amygdala Response is associated with Trait Anxiety (i.e., decrease in activity from early to late trials)

Conclusions The behavioral and imaging studies of emotion regulation and self control provide evidence for: -significant individual and developmental differences in these abilities. -potential for change in these abilities by social and psychological contexts.
Conclusions The behavioral and imaging studies of emotion regulation and self control provide evidence for: -significant individual and developmental differences in these abilities. -potential for change in these abilities by social and psychological contexts. All 3 can lead to imbalances between control and emotional systems, yielding suboptimal choice behavior. and require careful consideration when considering approach for behavioral change!
