Neurons - are they arrested in G0 or G1?

I have always thought G0, but I got a question wrong saying that they're in extended G1. Apparently, they're the same sometimes? Can someone clarify?

"G0 phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle. G0 is sometimes referred to as a "post-mitotic" state, since cells in G0 are in a non-dividing phase outside of the cell cycle."
