I have had it with these #@$&! snakes in this #@$&! scanner!

How does the brain encode courage in a real-life fearful situation that demands an immediate response? In Fear Thou Not: Activity of Frontal and Temporal Circuits in Moments of Real-Life Courage, volunteers who fear snakes had to bring a live snake into close proximity with their heads while their brains were scanned using functional magnetic resonance imaging (fMRI). Oh, do watch the video.
