This talk will be a development of research that builds on ideas about communication systems in the brain. One version was presented by Dr. Martha Gillette and her collaborator in a paper published in 1987 where she wrote, "Oscillations in VP secretion and neuronal firing rate potentially represent separate modes by which the SCN transmit time information to other brain regions. The electrical oscillation may relay time-of-day by efferent neuronal output along a limited number of specialized circuits. The VP secretory rhythm potentially modulates daily rhythm in physiology by a generalized neurohormonal effect”. Now- more than 3 decades later- the evidence flows forth
