Fig. 2.13 Globus pallidus interna (medial segment) on axial, coronal, and sagittal planes
of Brodmann’s areas, defined based on their neuronal organisation, have since been
correlated closely to diverse cortical functions.
2.3 Vascular Neuroanatomy
The knowledge of cerebrovasculature is crucial in stroke, vascular, and tumour
surgery as well as interventional neuroradiology. The complete cerebrovasculature
is highly complex and variable (Fig. 2.16). It is subdivided into:
• Arterial system
• Venous system with the cerebral veins and dural sinuses
2.3.1 Arterial System
2.3.1.1 Parcellation of Arterial System
The brain is supplied by two pairs of arteries, left and right internal carotid arteries
anteriorly and left and right vertebral arteries posteriorly forming the basilar artery
(Fig. 2.17a), that are interconnected by the circle of Willis (Fig. 2.21).
