Locating the central sulcus in a structural MRI. A schematic guide to find the central sulcus on the basis of anatomical landmarks in axial (left), parasagittal (middle) and midsagittal (right) sections. The course of the central sulcus is displayed in yellow, and the superior frontal sulci (left) and cingulate sulcus (right) appear in green. This anatomical information should be complemented with MEG information: SEF recordings for pinpointing the somatosensory cortex just posterior to the central sulcus and cortex–muscle coherence recordings to identify the primary motor cortex just anterior to the central sulcus.
