…This gets into the bowels of the brain, the reptilian brain, so to speak, to the roiling, evolutionarily archaic areas that operate in that primeval brew of neurotransmitters, heavy metals and glyco-fiber, the brain stem.

Glyco-fiber should not be part of a balanced diet.

The locus coeruleus is, for one thing, blue, apparently, from melanin that is located in the substantia nigra radiating out.

Who says blue isn’t found in nature?
pron.: nigh-gr-uh

(For more explanation, here is a terrific Youtube neuro class, about 18 minutes. ) But, more to the point, this evolutionarily archiac little bundle of neural controls is key in how we respond to danger, or what we perceive as danger. Where the brain detects a threat, the amygdala and limbic system are activated and transmit signal to projections leading to the locus coeruleus. …

The wiring from the locus coeruleus goes up through the midbrain to connect with the amygdala and other areas. The brain midline defects apparently found in psychopaths (here) seem to provide a wide open highway for the reptilian signals . ….
