Is it that something that is neuronal has to do with neurons, while something that is neural has to do with nerves or the nervous system? Is something that is neuronal necessarily neural? Or does it depend on the context? E.g., if we have that,
A neural stem cell can go on to become a glial cell or neuron.
and
A neuronal stem cell is committed to become a neuron.
Is the latter no longer a neural stem cell because it has lost its ability to become a glial cell?
