1. SYN: 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 dorsal surface of the corpus callosum; behind the latter's splenium 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.
