Course of large vessels. Three-dimensional rendering of the vascular frequency maps, thresholded at levels of 60% vascular frequency, showing the most likely course of the basilar artery (BA), the pericallosal artery (PC), and the insular arteries fanning out of the middle cerebral artery (CM). (A) View of the anterior face of brain from below, after removal of the most anterior part of the temporal and prefrontal lobes. (B) Latero-posterior view, after removal of most of the left hemisphere. (C) Likely course of the posterior cerebral artery (CP) along the medial border of the hippocampus (transversal slice, after removal of upper part of the brain). Abbreviations: a, artery; aa, arteries; int, internal; cer, cerebral; car, carotis.
