Abstract

Cortical areas in rodents have been basically characterized by its cytoarchitecture, connectivity or by physiological parameters. In this study we show that they are revealed by distribution patterns of proteoglycans and parvalbumin-immunoreactivity. Brains of young adult Mongolian gerbils (Meriones unguiculatus) and Wistar rats were cut into series of transversal sections. Proteoglycan components were detected using the N-acetylgalactosamine binding Wisteria floribunda agglutinin (WFA) and antibodies against chondroitin sulphate proteoglycan (CSPG). Differences between cortical areas were found to exist with regard to the occurrence and the density of perineuronal nets, but were also expressed in varying staining intensities for WFA and CSPG of the neuropil. Primary neocortical areas (somatosensory, auditory, visual cortex) were characterized by an intense neuropil staining in layer IV and the upper part of layer VI. Using the same methods strong labelling was also typical of the neuropil in the retrosplenial cortex, of layer Ia in the prepiriform cortex and the hippocampal CA3 field. In tangential sections cut from gerbil cortical hemispheres, some of the heavily lectin-stained cortical areas were sharply delineated from adjacent faintly labelled regions, others showed more diffuse borders. In the rat, the area-specific staining for WFA was less clearly expressed than in the gerbil. Immunocytochemistry of the calcium-binding protein parvalbumin in alternate sections showed labelling patterns of neuropil which resembled those of WFA-binding and CSPG-immunoreactivity in the entire neocortex and hippocampus. From these results it can be concluded that functional peculiarities of cortical fields may not only be determined by neuronal network parameters but also by the spatial arrangement of extracellular matrix proteoglycans.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
