In human anatomy, the occipital lobes and the back of the head are posterior but not caudal to the frontal lobes and the face.
Most research using musical stimuli has focused on self-reported "chills" which is a subjective experience, unlike piloerection which is an objectively quantifiable physiological reaction. However, research has shown that self-reported piloerection does not correspond to observed piloerection.
