Best Answer: There are several nuclei involved, but they are primarily located in the medulla and pons, both of which are considered part of the brain stem.

Princess Juliana, who has died, aged 94, of a lung infection, was Queen of the Netherlands from 1948 to 1980, when she abdicated in favour of her daughter, Queen Beatrix.
