Starting Point: Intraparietal sulcus
Direction: Superior to Inferior
Ending Point: End of sulcus
Notes: Offshoot from nearby the middle of the Intraparietal sulcus. It is always the posterior border of the angular gyrus. Never let it interfere with the posterior branch of the post central. Should resemble a “T” as it comes down from the top of the Intraparietal sulcus into the depths of the angular gyrus.
