Central Sulcus (#1)

Starting Point: Top view, close to midline

Direction: Superior to Inferior

Ending Point: Side view, superior to Sylvian fissure

Notes: Generally unambiguous. The axial view can be helpful because the sulcus has a characteristic bend (moving lateral bends to the anterior. See Figure 1a). Do not cross over any gyri as you move inferior. The superior extent tends to curve posterior as it moves towards midline.
