The cell bodies of these neurons or the relevant neurons are actually up near the neck. So you can think of them as a clump of grapes, 'cause cell bodies tend to be round or oval-ish. And then they send a process that we call an axon in one direction out to the gut and they'll send another process up into the brain. And that little cluster near the neck that's relevant here is called the nodose ganglion, N-O-D-O-S-E.
