2008 Brain  
A local index of ICC in a circumscribed brain primary area was altered in mildly disabled RR-multiple sclerosis patients, also in absence of any impairment of central sensory conduction.  ...  When matched with a control population, multiple sclerosis patients showed a reduced ICC combined with the complete loss of the finger-dependent functional specialization in S1 cortex of the dominant hemisphere  ...  On these bases, the dynamic gamma band phase locking measured by ICC is suggested as a code for finger dexterity, in addition to the magnification of somatotopic central maps.  ...
