Underactivation in the left temporal lobe results indiccate reduced socioemotional responses which explain the impulsive factor related to DBD's.

- decreased prefrontal cortical functioning
- decreased activity in left temporal pole
- decreased right dorsolateral prefrontal cortical functioning

The neurobiology of oppositional defiant disorder and conduct disorder: Altered functioning in three mental domains

Research Indicates that Youth with Oppositional Behavior display Underactivation in the Left Temporal Pole

Children with oppositional and conduct behaviors have poor top-down processing which results in poor emotional processing. 

FMRI Studies Display Underactivation in the Prefrontal Cortex in Children With Disruptive Behavior

- Punishment processing
- Reward processing
- Cognitive control


Three Mental Domains Associated with ODD Behavior


The decreased functioning in the dorsolateral prefrontal cortex explains the attention deficits associated with conducct behaviors of DBD's.
