Episode notes
What Is Emotion-Related Impulsivity?
- Emotion-related impulsivity involves chronic loss of self-control under high stress or emotion.
- It's distinct from other impulsivity forms like inattention or lack of perseverance.
Arousal, Not Just Emotion, Triggers Impulsivity
- High physiological arousal drives impulsivity beyond specific emotions.
- This explains impulsivity both in anger and excitement states like mania.
Right Inferior Frontal Gyrus Controls Impulses
- The right inferior frontal gyrus is crucial for impulse control and inhibition.
- Meta-analysis confirms its significant role, though other brain regions also matter.
