Finally, we predicted14 that if the remapping were at least partly cortical (rather than thalamic), then after deafferentation caused by central white matter lesions, one should observe sensations by referral from normal skin areas to the deafferented zones. Victims of the malady either think theyre masked even when they arent and/or cant bring themselves to physically remove their mask without psychological side effects which can manifest as real physical symptoms. We tested 18 patients with either arm amputation or brachial avulsion, and found that 8 patients systematically referred sensation from the face to the phantom limb.3,4 In many of them, there was a topographically organized map of the hand on the lower face region (Figure 2) and the referred sensations were modality specific.

Electrocortical analysis of patients with intercostobrachial pain treated with TENS after breast cancer surgery. Kevins adds that while shes looked online for support groups, she continually hits a dead end with people telling her theres nothing wrong with wearing a mask. How then could Mr. Wittgenstein feel a hand that was no longer attached to him? Certain drugs, such as ketamine (an anesthetic) and calcitonin (a hormone), administered prior to amputation surgery lessen the likelihood of development of later pain symptoms. For instance, if a stroke produces partial sensory loss, touching the spared "islands" of normal skin should evoke sensations referred to the deafferented regions.

It would be especially interesting to see if such an improvement also occurs on the face skin ipsilateral to amputation.
