Resting state functional organization in the human
cervical cord has only been scarcely explored. In this
study, we investigated the resting state functional
organization using a clinically relevant 3T whole body
MRI scanner from 24 healthy subjects. The correlation
coefficient computed from rsfMRI images between each
ventral or dorsal horn of different segments was used to
generate the correlation matrix. Segment C2 demonstrated
stronger correlations with other segments. Segment C2
has a stronger neural activity level than other
segments. Functional organization among segments was
detected, which demonstrated the functional network in
the human cervical cord.
