Cortical excitability changes after high-frequency repetitive transcranial magnetic stimulation for central poststroke pain.

abstract：:Two different modes of cutaneous sensory reinnervation are thought to be engaged following nerve injury: regenerative growth of the injured nerve and 'collateral sprouting' of neighboring intact nerves. Although both processes are well known from experimental preparations, there is little unequivocal documentation of ...
