2.2.2.3 Inferior Cortical Surface
The inferior surface of the cortex includes the frontal, temporal, and occipital lobes.
The frontal lobe comprises (Fig. 2.5):
• Straight gyrus
• Orbital gyri parcellated by the approximately H-shaped sulcus into the anterior,
medial, lateral, and posterior orbital gyri
The temporal and occipital lobes are subdivided by two sulci (the lateral
occipitotemporal sulcus and medial occipitotemporal (collateral) sulcus) into three
gyri (Fig. 2.5):
• Medial occipitotemporal gyrus whose temporal part constitutes the parahippocampal gyrus and the occipital part the lingual gyrus
• Lateral occipitotemporal gyrus (called also the fusiform gyrus)
• Inferior temporal gyrus
2.2.3 Deep Grey Nuclei
The deep grey nuclei are paired grey matter structures. The main deep grey nuclei
(other than the diencephalic nuclei discussed in Sect. 2.2.1) are (Fig. 2.6):
