• The most common structural central nervous system abnormalities in Schimmelpenning syndrome are hemimegalencephaly and ipselateral gyral malformations.
• In addition to the two gyral regions classically considered to constitute Broca's area ( pars triangularis and pars opercularis ), Broca's region includes pars orbitalis, the anterior portion of the left IFG.
• During 22-28 weeks of gestation, which is the critical period in fetal development of the dentate nucleus, gyral formation occurs extensively over the entire surface . and the most frequent neuronal types are medium sized to large neurons.
• To account for this problem, the coordinate-based " landmarks, which combines sulcal and gyral landmarks ( the groves and folds of the cortex ) and then finding an area well known for its modularity such as the fusiform face area.
• However, note that BA47 and pars orbitalis are not synonymous, as pars orbitalis specifically refers to a grossly visible gyral region and BA47 refers to the cytoarchitectonic features of brain tissue . " In vivo " neuroscience research almost exclusively discusses the gyral region, although the gyral and cytoarchitectonic terms are frequently used synonymously.

• For delineating the Entorhinal cortex, see Desikan RS, S間onne F, Fischl B, Quinn BT, Dickerson BC, Blacker D, Buckner RL, Dale AM, Maguire RP, Hyman BT, Albert MS, Killiany RJ . An automated labeling system for subdividing the human cerebral cortex on MRI scans into gyral based regions of interest.
• The elephant brain exhibits a gyral pattern more complex and with more numerous convolutions, or brain folds, than that of humans, primates, or carnivores, but less complex than cetaceans, although elephants have as many cortical neurons ( nerve cells ) and cortical synapses as that of humans, which is more than that of the cetaceans.
• "' Lissencephaly "'results from defective neuronal migration between the first and second trimester of gestation which causes lack of gyral and sulcal development, as well as improper lamination, There are five genes related to lissencephaly, including LIS1, the first to be discovered, and RELN . Apparently Cajal Retzius cells aren t affected in case of mutation in LIS1 gene, even though the product of this gene interferes with reelin interaction with their receptors.
