- •
We consider the human amygdala's anatomical sub-divisions in emotional processing.
- •
We analyze the sub-divisions' functional roles due to valence and/or arousal.
- •
Amygdala's laterobasal sub-division mediates valence.
- •
Amygdala's centromedial sub-division mediates valence by arousal interaction.
- •
None of amygdala's sub-divisions was found to mediate arousal.
