1. Introduction (0:00-1:16)
Welcome to The Museum of Emotional Brains! I’m Dominic. Today, we’re diving into the mind of Dio Brando, the main villain from JoJo’s Bizarre Adventure. Raised in poverty and adopted by George Joestar, Dio grew jealous of Jonathan Joestar’s wealth, status, and fiancée. He betrayed the Joestars, turned into a vampire using a mystical stone mask, and vowed to destroy JoJo, shouting: “I reject my humanity, JoJo!”
Envy like Dio's isn't unique. We all feel it. Today we explore the brain science behind envy. Let’s go!
2. What Is Envy? (1:16-2:00)
Envy is a negative social emotion, triggered when someone else has an advantage and we feel inadequate. Dio envied JoJo’s nobility and life.
It can be benign (motivating self-improvement) or malicious (involving hostility). Dio embodies malicious envy.
Envy activates brain areas related to social pain, notably the anterior insula (aIns) and dorsal anterior cingulate cortex (dACC). These regions react to envy as they do to physical pain.
3. The Anterior Insula (2:00-3:17)
The anterior insula, deep in the brain’s lateral sulcus, is part of the insular cortex. While the posterior insula senses pain and temperature, the anterior insula gives emotional meaning to those sensations.
It is central to the interoception network, translating bodily signals (like heart rate or gut tension) into emotional awareness. Without it, we may understand envy but not feel it.
4. Envy's Brain Circuit (3:17-5:11)
The aIns doesn’t act alone:
- rTPJ/rIPL distinguish self vs. others.
- dACC detects social gaps (“they’re better than me”).
- aIns transforms this into discomfort.
- vStr/vmPFC assess personal loss.
- Amygdala/dorsal insula activate if the envy is malicious.
- dlPFC manages emotion through cognitive control.
Dio’s envy likely overwhelmed this system, especially in the prefrontal cortex.
5. Empirical Evidence (5:11-6:25)
Takahashi et al. (2009) scanned 19 adults with fMRI. Participants imagined:
- A similar person succeeding (envy).
- That person failing (schadenfreude).
Results:
- Envy activated the anterior insula, especially when the person was similar.
- Schadenfreude activated the ventral striatum (reward center), releasing dopamine.
This supports the idea that envy is painful and others’ misfortune can feel rewarding.
6. When the Anterior Insula Fails (6:25-7:28)
Damage to the aIns slows emotional awareness. People might know others are doing better but won’t feel much. This is linked to alexithymia: struggling to identify or describe emotions.
Without envy, there’s no motivation—just emotional numbness.
7. Neuroplasticity (7:28-7:50)
The brain can adapt. Neuroplasticity means it can rewire. Though gray matter loss in aIns is hard to reverse, other areas (like dACC, somatosensory cortex, or the other insula) may compensate.
8. Could Therapy Save Dio? (7:50-9:31)
Dio’s brain likely overreacted to social threats. But therapy could help. Research shows:
- Aerobic exercise strengthens the link between PFC and aIns (Hotting & Röder, 2013).
- Emotion recognition training improves dACC regulation (Kober et al., 2019).
This might help reduce Dio’s sensitivity to status differences and calm his envy.
However, change requires weeks of effort. But with awareness and support, even Dio could change.
9. Conclusion(9:31-10:31)
The anterior insula is crucial in turning bodily sensations into emotional experiences like envy. Though often seen as shameful, envy has two sides: destructive when unmanaged, but motivational when controlled.
We all have Dio moments, but we also have the power to choose not to become him.
