Background/Aim:
The central area of the brain, including the pre- and post-central gyri with their vascular structures, is one of the most crucial regions to preserve in neurosurgical intervention. The central sulcus is also a landmark of utmost importance for neurosurgeons. Although the arteries supplying the central region have been briefly described, their exact course has not been studied. The aim of the study is to establish the position and course of the central sulcus artery in relation to the central sulcus and its convolutions.
Methods:
Computer-assisted three-dimensional (3-D) anatomical reconstructions of the central area and of the central sulcus artery were performed with the aid of neuronavigational software in 13 patients operated at the Montreal Neurological Institute (MNI).
Results:
The central sulcus artery was coincident with the central sulcus and course(s) was almost similar on both hemispheres.
Conclusions:
The knowledge of the exact course of the central sulcus artery is of paramount importance in cases of lesions or epileptic foci involving the central area. 3-D reconstruction with neuronavigation has proven to be a reproducible and reliable technique to provide the surgeon with the necessary surgical topographic anatomy of the central sulcus artery and central area.

The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect various areas...
