1. Important gyri are the precentral and postcentral gyri, for example. 2. Brodmann area 4 is part of the precentral gyrus. 3. The pyramidal cells of the precentral gyrus are also called upper motor neurons. 4. The VTh projects to upper motor neurons in the primary motor cortex ( precentral gyrus ). 5. SLF III connects the rostral inferior parietal cortex which receives information from the ventral precentral gyrus. 6. More specifically, subvocal rehearsal and verbal maintenance are associated with the posterior left precentral gyrus. 7. However, the precentral sulcus may sometimes be divided into three parts or form one continuous sulcus. 8. The primary motor cortex is located on the precentral gyrus and is often visualized as the motor homunculus. 9. The primary motor cortex or precentral gyrus, is one of the most important areas in the frontal lobe. 10. The precentral gyrus is the most posterior gyrus of the frontal lobe and it lies anterior to the central sulcus.
