Spine "Chills"?

Question

Is there a scientific explanation for the "chills" I experience when I read or hear something I consider profound? I suppose these are commonly referred to as "spine chills" although, I don't experience them in my spine. The terminology could be bettered, is there an official word for this?

Answer 1

some kinda neurotransmitter release...you know, like adrenaline rushes

Answer 2

Emotions have strong physiological impact on the body.

Scary things make your hair stand on edge.  It's your body reacting to the situation and to your emotional state.
