This study reveals significant hemispheric and sex-based variations in the paracingulate sulcus anatomy. Understanding these differences in the anterior cingulate cortex is crucial for surgical planning and safe lesion access.
Area of Science:
- Neuroanatomy
- Neurosurgery
Background:
- Cerebral sulci and gyri exhibit individual morphological differences.
- The cingulate sulcus is a key landmark for surgical approaches to adjacent pathological lesions.
- Anatomical variations in the anterior cingulate cortex are vital for determining safe surgical entry routes.
Purpose of the Study:
- To investigate anatomical variations of the paracingulate sulcus.
- To identify hemispheric and sex-based differences in paracingulate sulcus morphology.
Main Methods:
- Retrospective analysis of magnetic resonance imaging (MRI) data from 149 healthy volunteers.
- Investigation of cingulate and paracingulate sulcus anatomy in human cadaveric brain hemispheres.
Main Results:
- All participants (100%) had cingulate sulci.
- Three paracingulate sulcus patterns were identified: prominent, present, and absent.
- The paracingulate sulcus was more prominent in the left hemisphere (32.21%) and absent in the right hemisphere (48.99%).
- Significant differences were observed in the presence/absence of the paracingulate sulcus between hemispheres (p=0.019).
- The paracingulate sulcus appeared more prominent in males than females, with females having a higher incidence of absence.
Conclusions:
- The paracingulate sulcus exhibits significant hemispheric and sex-based anatomical variations.
- Awareness of these variations in the anterior cingulate cortex is essential for neurosurgical orientation and planning.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...
