=====Pericallosal pial plexus=====
These branches were directed toward: 1. the upper surface of [[corpus callosum]] (3-6 branches, mean 8), 2. the depths of the sulcus corporis callosi (4-13 branches, mean 7), and 3. the cingulate gyrus (1-10 branches, mean 5). All the vessels composing the pericallosal pial plexus have a uniformed caliber of 0.9-0.6 mm at their origins, and 0.7-0.3 mm after branching. In 9 cases a longitudinal vessel within the [[stria longitudinalis medialis]], connected with the pial plexus was found

pial plexus in man. Anat Anz. 1989;169(2):125-30. PubMed PMID: 2589635.)).

A detailed examination of the anatomic features of all the main arteries of supply revealed anastomoses within the callosal sulcus that formed the [[pericallosal pial plexus]]. This network supplied the corpus callosum, the radiation of the corpus callosum, and the cingulate gyrus
