Anatomy and function
The postcentral gyrus contains primary somatosensory cortex, which processes touch, proprioception and other sensory information. It lies next to the precentral gyrus, across the central sulcus.
Where to look in the model
Both postcentral gyri are highlighted, behind the central sulcus.
What this view does not establish
The highlighted extent follows a gyral parcel, rather than the cytoarchitectonic boundaries of Brodmann areas 3, 1 and 2.
Open in 3DSources and precision
Cortex uses the FreeSurfer fsaverage5 template surface, with 10,242 vertices per hemisphere. Functional references use selected Destrieux sulcal and gyral parcels. Deep structures use fsaverage aseg segmentations. The Sereno2020 cerebellar research surface preserves folial geometry, but comes from another specimen; its assembled placement is schematic, without medical registration across templates. Arterial paths are manually drawn teaching schematics, not CTA/MRA reconstructions.
An educational schematic prototype for understanding spatial relationships. Item-by-item independent neuroanatomical review is pending. Functional highlights are not results of an individual examination and do not support individual diagnosis or treatment decisions.
