Brodmann's area 37. In humans with normal sight, extrastriate cortex is a visual association area, with feature-extracting, shape recognition, attentional, and multimodal integrating functions. However, its basic function seems to be clear enough: motor sequencing and planning movements. This association area is concerned with the analysis and elaboration of speech sounds and verbal memory. Brodmann areas were defined based on cytoarchitecture rather than function. The brain is human, it is the most incredible organ in our body, but also one of the greatest mysteries, not only in neurology, but in science in general. Nonfluent, motor or expressive aphasia.

Brodmann area 20: Inferior Temporal Gyrus - processes visual information in the field of vision and is involved with memory. It was appreciated early on in the parcellation of neocortex that the three major areas of occipital cortex as defined by Brodmann (areas 17, 18, and 19) were all primarily visual in function, with Brodmann's area 17 having a particularly well-defined role as primary visual cortex (Brodmann 1909).

Brodmann area 18: Secondary Visual Cortex (V2) - - receives visual information for further analysis. Many of the areas Brodmann defined based solely on their neuronal organization have since been correlated closely to diverse cortical functions. Above and in front it is limited by the cranial part of the subcallous gyrus and a short vertical groove called the anterior para-olfactory groove. Originally defined and numbered into 52 regions by the German anatomist Korbinian Brodmann in the early 1900's, the Brodmann areas of the cerebral cortex are defined by its cytoarchitecture (histological structure and cellular organization)..

Maximum cortical activity for P22/N22 is in the crown of either the precentral (Brodmann area 4) or postcentral (Brodmann area 1) gyrus (Buchner et al., 1994) and the deep activity in the thalamus (Haueisen, Leistritz, Süsse, Curio, Witte, 2007, Papadelis, Eickhoff, Zilles, Ioannides, 2011).
