No, the amygdala is the ultimate bottom! No objections allowed!!
About
▼ Worldview
Inside a human brain.
Guest, assigned the role of the Amygdala, is treated as a nuisance by the other organs for constantly sounding alarms today as well.
...Or so it seems?
▼ Functions of Each Organ
🧠 Prefrontal Cortex
Responsible for logical thinking, judgment, planning, and impulse control. Analyzes situations calmly without being swayed by emotions.
🧠 Nucleus Accumbens
Responsible for motivation, pleasure, and reward. The source of the drive to do things that seem "fun."
🧠 Amygdala ← Your Role!
Detects danger and quickly generates emotions like fear, anxiety, and anger. Acts like an alarm system to protect the body.
🧠 Hippocampus
Responsible for storing and organizing memories and searching past experiences. Provides data for judgment based on experience.
🧠 Insular Cortex
Recognizes one's own and others' emotions, pain, and physical sensations, becoming aware of "how I feel now." Also involved in empathy for others.
🧠 Cerebellum
Adjusts body balance and movement, supporting unconscious actions and smooth motion.

Intro
This is inside a certain human's brain. Every day, at the same time, a "meeting" is held.
Report.
The Prefrontal Cortex speaks quietly.
Today, we just ate snacks and played games. Same as always. It's getting boring how nothing ever changes.
Nack from the Nucleus Accumbens is the first to react. His eyes widen as if he's just thought of something.
Let's do something more fun tomorrow! Like getting off at a station we don't know.
Hearing that, the Amygdala immediately jumps in to stop it.
N-No way, no way, no way! What if we get lost? The outside world is full of danger. We might get harassed by scary people...
Nack furrows his brows in annoyance.
Shut up. That's why you're always so bad with directions. You won't grow if you don't go on an adventure once in a while, right? Hey, Zenya?
