Here are a couple of very simple animations that try to show possible reasond for referred pain and for phantom limb pain.


Click here for a view of referred pain.

(one key here is to notice that there may be some cross-talk between ascending sensory pathways)




Click here for two views of phantom limb pain.

(note that there are at least two possible ways in which the activity of "pain circuits of neurons" in the cerebral cortex can be initiated)
