...In fact, there is little anatomical evidence that the face-elicited activity in SI is mediated by the growth of new cortico-cortical projections: Very few axons cross the face–hand boundary in SI of intact animals (see [57] for analogous results in humans revealed with neuroimaging) and deafferentation of the hand region does not result in any measurable increase in these boundary-crossing projections [58]....

...…more limited than initially thought, and that instead the functional changes previously observed in S1 following input loss could be attributed to reorganisation in sub-cortical areas in the afferent pathway, principally the brainstem (Jain et al., 1998; Kambi et al., 2014; Chand and Jain, 2015)....

...It has been suggested that the initial remapping triggered by deprivation will become refined by inputs due to daily hand usage involving compensatory behaviours (Churchill et al., 1998; Elbert et al., 1997)....

...However, a recent definitive study showed that in monkeys with chronic lesions of the dorsal column of spinal cord that had resulted in large-scale map reorganization of hand and face representations in area 3b, nevertheless showed a striking absence of new intracortical projections across the hand–face border (Chand and Jain 2015)....

...…of brain plasticity is of interest for development of brain– computer interface devices and neuroprostheses because postinjury plasticity can undermine control of devices, or if properly managed, facilitate a better interface (e.g., Enzinger et al., 2008; Jain, 2010; Collignon et al., 2011)....
