gustatory cortex

The term gustatory cortex refers to the areas of cerebral cortex involved functionally in taste perception. The locations to which it is attributed varies by species, by method of detection, and by author. In primates it involves the frontoparietal operculum and the anterior insula. fMRI studies in the human suggest that the primary areas are in the ventroanterior part of the right anterior insula with smaller areas located bilaterally in dorsal parts of anterior insula and the long insular gyri. Areas in which gustation is associated with other functions include all of the ventral part, and a small area near the dorsal boundary of, the anterior insula ( Fig. 3 in Kurth-2010b ). All studies of the macaque agree to a location on the inner and horizontal surfaces of the frontoparietal operculum, the portions of the postcentral gyrus and the precentral gyrus that overlie the dorsal part of the insula, which are identified as area OFO of Roberts ( Mesulam-1984 ) or area Gu of Paxinos (macaque) ( Paxinos-2009a ). That area receives a direct projection from the gustatory relay nucleus in the thalamus, i.e., the parvicellular part of the ventral posteromedial nucleus (VPMpc). Reports differ with regard to the internal structure of the frontal operculum area; some label it granular ( Mesulam-1984 ), others dysgranular ( Pritchard-2012 ). Additional projections have been traced to adjacent dorsal parts of granular insula and dysgranular insular cortex (Roberts). Some have interpreted these to represent secondary gustatory areas ( Sewards-2001 ). In the rat ( Swanson-2004 ) and mouse ( Hof-2000 ), the gustatory cortex is identified with the dysgranular insula.

Models Where It Appears
Functional CNS Model - Rat

The Functional CNS Model - Rat (FMrat) ( Swanson-2004) is one of three hierarchical models representing the internal organization of the central nervous system (CNS). The others are the Structural CNS Model - Human (SThmn) and the Functional CNS Model - Human (FMhmn). The FMrat model represents the basic organization of the mouse ( Hof-2000 AMBA-2024 ) and, presumably, other rodents. Functional CNS models differ from structural models in that structures are defined and named by connectivity rather than by proximity to other structures at the same level. Functional models are more useful for representing longitudinal components of are grouped based on information drawn from multiple neuroscientific disciplines. such as connections, neurochemical characteristics, and role in physiogical and behavioral processes. While the Functional Model was developed primarily for an atlas of the rat brain ( Swanson-2004 ), the hierarchical organization of structures is for the most part applicable to the human, macaque, mouse and other mammalian brains as well. Structures at lower levels of the Functional CNS hierarchy are largely the same as in the Classical and Developmental Models, i.e., they were originally identified by stains for gray matter (Nissl substance) and white matter (myelin). At the next higher level they are grouped into basic connectional and functional systems of the CNS, such as the subcortical sensory systems, the brainstem motor system and the behavioral state system. At the highest levels CNS structures are grouped on the basis of dissection and embryologic precursors into cerebrum ( cerebral cortex and cerebral nuclei ), cerebellum, and cerebrospinal trunk.
