Inferior Temporal Gyrus Protocol

  1. The inferior temporal gyrus is parallel to the superior temporal gyrus and the middle temporal gyrus. The superior boundary of the inferior temporal gyrus is inferior temporal sulcus and inferior boundary is the lateral occipito-temporal sulcus. The anterior end is where the lateral occipito-temporal sulcus and the inferior temporal sulcus meet. The posterior end is quite variable but is generally found where the inferior temporal sulcus ends, near the occipital notch. A 3D object is helpful in finding these boundaries. Where the two sulci are unclear make sure that the width of the gyrus is fairly consistent. (Fig. 1, Fig. 2, Fig. 3, Fig. 4)
  2. Begin masking in the coronal view where the lateral occipito-temporal sulcus and inferior temporal sulci meet. Mask everything between these two boundaries. Continue masking until the inferior temporal sulcus is no longer visible. (Fig. 5, Fig. 6, Fig. 7)
