About 5 centimetres (2.0 in) in front of the occipital pole of the human brain, on the infero-lateral border is an indentation or notch, named the preoccipital notch.It is considered a landmark because the occipital lobe is located just behind the line that connects that notch with the parietoccipital sulcus.
The maps for visual areas are retinotopic, meaning that they reflect the topography of the retina: the layer of light-activated neurons lining the back of the eye. In this case too, the representation is uneven: the fovea —the area at the center of the visual field—is greatly overrepresented compared to the periphery.
That is, the legs and trunk fold over the midline; the arms and hands are along the middle of the area shown here; and the face is near the bottom of the figure. Because Brodmann area 4 is in the same general location as primary motor cortex, the homunculus here is called the motor homunculus.
an imaginary line drawn from the preoccipital notch to the lateral sulcus posteriorly. The superior temporal gyrus contains several important structures of the brain , including: Brodmann areas 41 and 42 , marking the location of the auditory cortex , the cortical region responsible for the sensation of sound ;

The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 cm in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parieto-occipital sulcus (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure ...
The term Brodmann area 8 refers to a cytoarchitecturally defined portion of the frontal lobe of the guenon.Located rostral to the arcuate sulcus, it was not considered by Brodmann-1909 to be topographically homologous to the intermediate frontal area 8 of the human.
Brodmann area 10 (BA10, frontopolar prefrontal cortex, rostrolateral prefrontal cortex, or anterior prefrontal cortex) is the anterior-most portion of the prefrontal cortex in the human brain. [1]
