Thanks to the vagus nerve, the emotions we feel are displayed on our faces and in the sound of our voices. […]
The brain science of fear: Scaring the "fearless"?

This woman had Urbach-Wiethe disease, a condition that causes the amygdala to calcify – it hardens and shrivels up. Now, we know that the amygdala is responsible for processing stimuli related […]
