"It is the largest superficial vein on the lateral surface of the parietal or frontal lobe that connects the superior sagittal sinus and the superficial middle cerebral vein (of Sylvius). It usually runs in the post-central sulcus 1 draining the adjacent cortex, but can be found in the central sulcus or anterior to it 5."
"It is eponymously named after French surgeon and anatomist Jean Baptiste Paulin Trolard (1842–1910) who studied the anastomotic veins of the brain 3."
