Cortical gyri and sulci From Gray’s Anatomy (the book!)

* Parietal Lobe Frontal Lobe Temporal Lobe Peri-sylvian cortical areas are associated with language Parietal Lobe * Broca’s Area Frontal Lobe Sylvian fissure Wernicke’s Area Temporal Lobe Heschl’s gyrus (Primary auditory Cortex, A1) Superior Temporal Gyrus

Cortical Areas Involved in Phonemic Processing Inferior Frontal Lobe 44, 45: Broca’s Area (on inferior frontal gyrus) PCG: precentral gyrus Inferior Parietal Lobe SMG: supramarginal gyrus AG: angular gyrus Temporal Lobe H: Heschl’s Gyrus aSTP: anterior superior temporal plane pSTP: posterior superior temporal plane STG: superior temporal gyrus MTG: middle temporal gyrus STS: superior temporal sulcus I: Insula (from Caplan and Gould, 2003)

Premotor Cortical Areas Somatotopic organization of the medial and lateral motor cortex in the monkey, showing the arm and leg representations. (ArSi, arcuate sulcus, inferior limb; ArSs=arcuate sulcus, superior limb; CS=central sulcus; M1 =primary motor cortex; PMd=dorsal premotor area; PMv=ventral premotor area; PS=precentral sulcus; SGm=superior frontal gyrus, medial wall; SMA=supplementary motor area; pre-SMA = presupplementary motor area; SPcS=superior precentral sulcus.)
