...…such as transection of the dorsal columns (10 –14 mm, and sometimes more that 20 mm, Jain et al., 2008) or transection of dorsal roots (Pons et al., 1991), is beyond what can be mediated by normal connections in the brain, reorganization must involve axonal sprouting (Kaas et al.,…...

...We extend these observations and show that chin representation also has only few connections across the hand– face border, which is important because it is the chin representation that expands as a result of massive deafferentations (Pons et al., 1991; Jain et al., 1997, 2008)....

...…at multiple sites along the somatosensory pathway, it has been proposed that reorganization could take place at all these sites independently, or changes at upstream areas could be a reflection of the downstream reorganization (Pons et al., 1991; Kaas et al., 1999; Jones, 2000; Kambi et al., 2014)....
