No problem! I've been diving into the brain of late, with research into psychedelics. And there are quite a few interesting studies that tackle how the brain reacts to different facial expressions; anger, happy, sad. When the brain sees an angry face, or a depressive face, it signals the amygdala, and sets off a chain of reactions. I touch on it here, Conquering Fear!

I'm big into psychology and psychedelics as well. I'll have to check out your post. It sounds interesting.
