I recently posted an answer to the question "How do parasites reprogram brains?". After editing, my answer described three different examples from neuroparasitology. In each of these, the way in which the behavior-altering parasite affected the brain of its host, or otherwise controlled its behaviour, was different in at least one way. (Even though researchers do not have a complete understanding of the mechanisms involved, quite a lot is known!)
I would like to come back and add more examples of neuroparasitic mechanisms, and (behavior-altering parasite/"zombie" victim) pairs that exhibit each one. However, I'm aware that this could lead to a very long answer, with the risk that interested readers might not know I'm updating it.
I'd like some guidance as to which of these the users of the site would consider best-practice:
To change my answer into a community wiki. This would make it clear to other users that the answer was open to further editing, and to having more examples added, over time. On the other hand, it could still lead to the answer being a very long posting. And if I understand correctly I would lose the rep I've already gained from upvotes on that answer.
Split my existing answer up into three separate answers. Then post a new answer for each successive means of behaviour control I've researched with at least one accompanying example. This has the disadvantage that the first answer now has more upvotes than it actually earned (upvoters were voting on the original answer with multiple examples.)
It could also look as though I'm trying to game the reputation system, by allowing users to upvote each of my answers individually - whereas before there was only one vote on my one answer per user.
Post a new answer for each new example as described above, but don't split up the original answer.
Continue just to add new examples to the original answer, without making it a community wiki.
My thanks for any and all advice! I'm new to this site, so I do appreciate your guidance.
