          Why do we gasp, jump and go pale when we're frightened? It all comes down to a tiny, almond-shaped structure in the brain that's called the amygdala. Matthew Orr, Alex Hogan/STAT

          It feels like your body reacts a million different ways when you get scared — the blood rushes out of your face, you jump, you gasp, your heart starts racing.

          It all comes down to a tiny, almond-shaped structure in the brain that’s called the amygdala.

          It’s responsible for kickstarting your “startle response.” That sends out a distress signal to the hypothalamus, and from there, your brain makes the call between fight and flight.

          Learn more about the science of fear in the new episode of “Boddities.”
