Where do the electrons go in a Neutron Star?

I have been reading a little bit about neutron stars and I think they are really fascinating. However, I've never understood where the electrons go when the atoms collapse into neutrons. It was explained to me that the protons in the nucleus absorb the electrons, giving the atom a neutral charge. But, neutrons are made up of 2 down quarks and an up quark without an electron in it. So what happens to the electron?

They combine with the protons to form neutrons (an up becomes a down), while a neutrino shoots out. So to answer the question of where the electron "goes," the electron-ness is carried away in the form of the neutrino, while the charge is cancelled out by the proton's.
