What does it mean if a person has almost no amygdala activation?

Question

I watched a documentary recently (Free Solo), and in one part of the film, it showed via an MRI that the main character has ‘no activation in your amygdala’. What does this mean?

Answer 1

The amygdala processes fear. If someone’s amygdala doesn’t active they won’t feel fear. This means they are more likely to take risks and do dangerous stunts.
