abstract = {An increasing number of neuroimaging studies addressing
patients with corticobasal syndrome use macroscopic
definitions of brain regions. As a closer link to
functionally relevant units, we aimed at identifying
magnetic resonance–based atrophy patterns in regions
defined by probability maps of cortical microstructure. For
this purpose, three analyses were conducted: (1) Whole-brain
cortical thickness was compared between 36 patients with
corticobasal syndrome and 24 controls. A pattern of
pericentral atrophy was found, covering primary motor area
4, premotor area 6, and primary somatosensory areas 1, 2,
and 3a. Within the central region, only area 3b was without
atrophy. (2) In 18 patients, longitudinal measures with
follow-ups of up to 59 months (mean 21.3 ± 15.4) were
analyzed. Areas 1, 2, and 6 showed significantly faster
atrophy rates than primary somatosensory area 3b. (3) In an
individual autopsy case, longitudinal in vivo morphometry
and postmortem pathohistology were conducted. The rate of
magnetic resonance–based atrophy was significantly
correlated with tufted-astrocyte load in those
cytoarchitectonically defined regions also seen in the group
study, with area 3b being selectively unaffected.},
