In principle, a headache is not a pain in the gray matter. Because the gray matter of the brain, in general, is not a receptor organ, but an analyzer – it does not have “pain”receptors. You feel uncomfortable with the receptors located in the tissues surrounding the blood vessel wall of the brain. It is fluctuations in the expansion and narrowing of blood vessels that cause headaches. “Neural connections” are just an established biochemical process between two neurons. This is not a bundle or coupling of cars, this is the establishment of feedback.
