  Not much is known profoundly about the physiology of fear, but
  here is a neuroscientific proposal for the etiology of emotion:

  In the Default Standard Model of the Mind as depicted above, we
  see a dangerous-looking dog through our visual memory channel.

  As the incoming image of a dog floods our visual memory channel,
  the successful recognition of the incoming image (not as a whole
  but as a widely disparate array of features as Nobel-Prize-ified
  by Hubel and Wiesel ca. 1961 --> Stockholm 1981), causes the con-
  cept or idea of "dog" to be activated in the semantic mind-core.

  By spreading activation (q.v. alibi), the gang of neurons for
 "dog" redeposits the remembered image of dog at the freshest ex-
  tremity of the advancing front of consciousness; activates the
  word "dog" or "chien" or "Hund" or "inu" or "sobaka" in auditory
  memory according to what language you are musing in; and strikes
  fear into our timid, cowering brain by activating a meta-network
  of neurons tying in our rational mind-processes with our primitive
  physiological responses to clear and present dangers:  CAVE CANEM.
