abstract = {Stroke is a devastating disease leading to cell death and
disconnection between neurons both locally and remote, often
resulting in severe long-term disability. Spontaneous
reorganization of areas and pathways not primarily affected
by ischemia is, however, associated with albeit limited
recovery of function. Quantitative mapping of whole-brain
changes of structural connectivity concerning the
ischemia-induced sensorimotor deficit and recovery thereof
would help to target structural plasticity in order to
improve rehabilitation. Currently, only in vivo diffusion
MRI can extract the structural whole-brain connectome
noninvasively. This approach is, however, used primarily in
human studies. Here, we applied atlas-based MRI analysis and
graph theory to DTI in wild-type mice with cortical stroke
lesions. Using a DTI network approach and graph theory, we
aimed at gaining insights into the dynamics of the
spontaneous reorganization after stroke related to the
recovery of function. We found evidence for altered
structural integrity of connections of specific brain
regions, including the breakdown of connections between
brain regions directly affected by stroke as well as
long-range rerouting of intra- and transhemispheric
connections related to improved sensorimotor behavior.},
