However, "the question specifically relates to PNS vs CNS": is that true? It seems the question is about the retina, which, as your PS notes, is often considered part of the CNS. My suggestion, which of course is your decision to accept or reject, would be to amend at least your 'simple answer' to make clear up front the ambiguity or context-dependence of the term "interneuron." | |
| Jun 9, 2017 at 15:18 | comment | added | AliceD♦ | @BryanKrause Considering your first comment, the question specifically relates to PNS vs CNS, so I think the approach of the answer is OK. Concerning your last comment please read the post scriptum | |
| Jun 9, 2017 at 15:16 | comment | added | Bryan Krause♦ | Also by some definitions, the retina is special among sensory systems in that it actually develops from brain tissue and therefore is often considered part of the CNS. Based on that and the rest of your definitions, then, bipolar cells would not be considered "sensory" because they are already part of the CNS, so they are just as much interneurons as any of the relay neurons of the spinal cord. | |
| Jun 9, 2017 at 15:14 | comment | added | Bryan Krause♦ | I mostly like your answer, but from the perspective of someone that studies the brain (and cortex specifically), I would generalize to say that you are relying on definitions of interneurons that are used when describing the relationship of the brain to the periphery. For people focusing within brain structures, it is definitely not true that all cells of the brain are thought of as interneurons; it is also not true that interneurons are reserved for GABAergic cells, although this is common, because other cell types like spiny stellate cells in L4 of neocortex are also called interneurons. | |
