"We know that some chemicals utilize common receptor sites. Most of these are chemicals are similar in structure. Also, there are several groups of chemicals that react on common receptor sites. I strongly speculate that oligodendrocytes are like genetic chemical libraries with millions of key holes awaiting a trigger. It can also be (strongly) suggested that these keyholes were created by human exposure to chemicals, many of which came from ethnobotanicals that are still today demonized."
