• the bundle extends from the anterior perforated substance back over the dorsal surface of the corpus callosum
• behind the splenium of the corpus callosum, it curves downward, then forward in the white matter of the parahippocampal gyrus

• the cingulum consists largely of fibers from the anterior thalamic nucleus to the cingulate gyrus & parahippocampal gyrus
• it also contains association fibers connecting the cingulate gyrus & parahippocampal gyrus with the frontal cortex & with each other
