| STSp | Posterior superior temporal sulcus |
22 | A = A vertical plane drawn from the anterior extent of the transverse temporal gyrus P = Angular gyrus and middle occipital gyrus and sulcus S = Angular and superior temporal gyrus I = Middle temporal gyrus |
| Fusiform gyrus |
Fusiform or lateral occipito- temporal gyrus |
37 | A = Anterior transverse collateral sulcus P = Posterior transverse collateral sulcus M = Medial occipito-temporal sulcus L = Lateral occipito-temporal sulcus |
| Visual | Inferior occipital gyrus and sulcus, middle occipital gyrus and sulcus, calcarine sulcus, and occipital pole |
17, 18, 19 | A = On the lateral surface, a line starting from the parieto- occipital fissure to the temporo-occipital incisure; the medial surface included calcarine sulcus extending to the precuneus P = Posterior occipital pole S = Superior occipital gyrus I = Lateral occipito-temporal gyrus |
Note. A = Anterior; P = Posterior; S = Superior; I = Inferior; M = Medial; L = Lateral.
