reprise:

I will go waaaay out on a limb and even name the brain structure in which a receiver mechanism may reside based on reasons it would take several chapters to explain. You could legitimately ridicule this conjecture once you understood the many issues involved and studied the emerging facts.
The brain structure is located at the interface with the Limbic Vesicles and connected to the amygdala.

What and where is the transmitter? I do not think there is one. I think it is inherent in a quantum field itself.
