📄 Feynman Technique Example: The Neuroscience of Fear

Step 1: Go Wide, Then Deep

Topic: The Neuroscience of Fear

What do I already know?

• Fear is a survival response.
• It’s mostly processed in the amygdala.
• Fear can be learned (e.g., through trauma) or instinctual (e.g., loud noises).
• The brain reacts before we’re even consciously aware of the threat.
• It prepares the body: heart races, muscles tense, pupils dilate.

Sources I used to go wider:

• Book: The Body Keeps the Score
• Article on NIH website about the amygdala
• Podcast with Dr. Andrew Huberman
• YouTube animation: “How Fear Works in the Brain”

Deeper questions (investigate these next):

• What role does the prefrontal cortex play in fear?
