1. Synonym(s): girdle
2. A well-marked fiber bundle passing longitudinally in the white matter of the cingulate gyrus; the bundle extends from the region of the anterior perforated substance back over the superior surface of the corpus callosum; behind the latter's splenium it curves down and then forward in the white matter of the parahippocampal gyrus; largely composed of fibers from the anterior thalamic nucleus to the cingulate and parahippocampal gyri, it also contains association fibers connecting these gyri with the frontal cortex, and their various subdivisions with each other.
[L. girdle, fr. cingo, to surround]

2. A well-marked fiber bundle passing longitudinally in the white matter of the cingulate gyrus; the bundle extends from the region of the anterior perforated substance back over the dorsal surface of the corpus callosum; behind the splenium of the latter it curves down and then forward in the white matter of the parahippocampal gyrus; composed largely of fibers from the anterior thalamic nucleus to the cingulate and parahippocampal gyri, it also contains association fibers connecting these gyri with the frontal cortex, and their various subdivisions with each other.
3. The lingual portion of an incisor or canine tooth, which forms a convexity on the cervical third of the crown.
4. The cervical third of the crown of a molar, which is the source of the developing cusps.

Lying under the cortex and curving around the midbrain, the cingulum bundle has a shape resembling a girdle or belt -- hence its Latin name.
[37] also revealed a significant correlation between changes of apathy subscores of FrSBe and FA decrease in WM underneath bilateral primary motor areas and in the right anterior cingulum bundle and superior longitudinal fasciculus.
(f-g) Shh- Tom labeling of axons in the cingulum (cg) and corpus callosum (cc) was similar in sham (f) and TBI (g) mice.
The MD values in the left cingulum were positively correlated with baroreflex sensitivity and negatively correlated with serum nuclear DNA simultaneously.
Altered WM in SZ's first relatives was reported in frontal lobe [27, 28], hippocampus [28], cingulum angular area [20], anterior limb of the internal capsule [29], areas close to the right middle and superior frontal gyri [20], forceps minor, and SLF [30].
The upper teeth from Napak XV are close in dimensions to those in the holotype maxilla (M 19084) and show no clear morphological differences, apart from those mentioned in the discussion concerning the M1, NAP XV 382'08, which has lingual morphology which is somewhat divergent from other specimens from the same locality, and different from the molars from Napak I, in that the separation between the protocone and lingual cingulum is clearly marked.
The mesoloph on M1 is well-developed, extends from the median mure to the labial cingulum, and is fused with mesostyle.
The word shingles comes from the Latin word cingulum, meaning belt.
