During your life you may have noticed getting a pimple then getting another pimple at just the same place symmetrically I think I've read an abstract noting that this is an authentic phenomena
Here at imminst where people would like to find the cytokine cascades n genes associated with cumulative decay this suggests a group of physiochemicals that either tell the symmetrical part to get weird OR there is a point upstream that controls two or more widely separated areas of tissue
Also, if medication on one area of a symmetric infection causes a change on its symmetric associate then that demonstrates a potentially nonneural communications aspect
any thoughts
