Orbital part of inferior frontal gyrus Cytoarchitectonically it is most closely represented by Brodmann area 47 (BA47). However, 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. Orbital part of inferior frontal gyrus The orbital part of inferior frontal gyrus also known as the pars orbitalis is the orbital part of the inferior frontal gyrus. In the human, this region is bordered by the triangular part of
