ABSTRACT

The motor cortex and the posterior parietal cortex are formed by a mosaic of anatomically and functionally distinct areas (Figure 9.1), reciprocally connected in specialized circuits working in parallel (see Rizzolatti and Luppino, 2001), allowing the transformation of sensory information into action. These circuits represent the basic elements of the motor system. Lateral and mesial views of the monkey brain showing the parcellation of the agranular frontal and posterior parietal cortices. Intraparietal, arcuate and cingulated sulci are shown unfolded. Agranular frontal areas are labelled with ‘F', similar to the von Economo classification for human frontal cortex (<xref ref-type="bibr" rid="c09_r99">von Economo and Koskinas, 1925</xref>) and defined according to <xref ref-type="bibr" rid="c09_r64">Matelli et al. (1985</xref>, 1991) and <xref ref-type="bibr" rid="c09_r2">Belmalih et al. (2009</xref>). Frontal eye fields (FEF) are defined according to <xref ref-type="bibr" rid="c09_r13">Bruce et al. (1985</xref>). All posterior parietal areas except those buried inside the intraparietal sulcus are defined according to <xref ref-type="bibr" rid="c09_r75">Pandya and Seltzer (1982</xref>) and <xref ref-type="bibr" rid="c09_r47">Gregoriou et al. (2006</xref>). The areas buried inside the intraparietal sulcus and V6A are defined according to functional criteria (for references see <xref ref-type="bibr" rid="c09_r82">Rizzolatti et al. 1998</xref>). AI: inferior arcuate sulcus; AS: superior arcuate sulcus; C: central sulcus; Ca: calcarine fissure; Cg: cingulate sulcus; DLPF: dorsolateral prefrontal cortex; IO: inferior occipital sulcus; L: lateral fissure; Lu: lunate sulcus; P: principal sulcus; PO: parieto-occipital sulcus; ST: superior temporal sulcus; VLPF: venrolateral prefrontal cortex. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203132746/8bec5f43-24c5-41d4-90e2-d043cdfbe19c/content/fig9_1_B.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
