Some migraine sufferers are letting doctors induce a headache so their brains can be studied with special MRI machines. Doctors say that at the end of the brain is a bump. And that bump is the very back of a person's head. It's where vision starts and then spreads. In migraine patients, once part of the vision system turns on and off, it stays off.
All headaches are probably fundamentally very similar.
According to Jordan, another amazing aspect of this discovery is that brain waves normally cross the whole brain in less than a second, but in a migraine it takes almost half an hour. Apparently, scientist's have never seen anything like it. This brain malfunction reportedly creates chemicals that trigger headache pain. So we can see what in the brain is the first event when a person gets a migraine.
