Even if A and B are both types of neurons. Yes, I do know that, and it means that whatever one says about this is going to be oversimplified. I deal with this sometimes by writing horrid run on sentences that use commas to separate what not just distinct but opposite possibilities for any given action or change in the nervous system. But it's not a reason not to talk about these things. As always, if you catch me getting something wrong (not just incomplete, which any statement will be) I urge you to let me know.
