Consider that 1) nipple response to stimulus is involuntary but 2) some of us have noted only one nipple reacting on occasion.
So would a stroke victim who's suffered full loss of one side of the body have a consistently unresponsive nipple, or would stimulus still arouse it - or would it respond in conjunction with the "unaffected" nipple as an involuntary neuro-response?

I am still interested by this question. Like, a stroke victim is still able to blink on the side affected by a stroke, so some involuntary response is intact. Maybe nipple response is just not bilaterally tied the way blinking is -- it just so happens that usually nipple stimulation (e.g., from cold weather) happens to occur to both sides simultaneously, but the nipples are not linked the way eyelids are? Although sensory stimulation is entirely different from involuntary muscle-response, so what I just said is probably totally irrelevant and wrong.
[Willing left nipple to erect. Failing.
Wait. They're both trying.
Feeling out which could act independently, if either.
Left seems to be the dominant nipple. Fascinating. Somehow I want a dominant nipple PSA to be created.
Still no measurable success.]
But I'm thinking more of pupil dilation. And now how researchers are using eye responses to help measure hearing. And now wondering what nipple response could help measure.
Nipple winks!

Dominant nipple! Sounds like a country song. I know I have a dominant armpit: the right one. It's always sweatier than the left.
