hmmmm. perhaps the mechanical movement of the toothbrush gives rise
to a vibration of the connective tissue which starts oscilating
at its own frequency, which signal is then recognized by the
facial neurons, upon which the brain finds a difference in frequency
between toothbrush and facial tissue, and this together is then
interpreted as an itch close to the nose ?
any ideas ?
