Inferior Temporal Sulcus

The Inferior Temporal Sulcus (ITS) forms the inferior border of the middle temporal gyrus, separating it from the inferior temporal gyrus. It may be difficult to identify because it is often formed by several independent sulcal segments. It is parallel to the STS and also starts anteriorly at the level of the temporal pole (1) and courses posteriorly. The origin can easily be identified on anterior coronal (2) or parasagital (3) slices. Image 4 shows several segments forming this sulcus. The sulcus extends into the occipital lobe where it ends (5).
