Objective To digitalise von Economo and Koskinas (1925) brain atlas and obtain values for layer width, cell count, neuron size from each cortical lobes

Background Morphological differences in the cortex made it possible to map out cortical cytoarchitecture (e.g., properties of cortical layers). The differentiation of cortical cytoarchitectonic fields provided by von Economo and Koskinas (1925), have been recently applied to Magnetic Resonance Images (MRIs). This digital atlas has enabled investigations of cortical microscopic parameters at the macroscale

Design/Methods The study included data on cytoarchitectonic properties (cortical layers, neuron count and size) using the von Economo and Koskinas (1925) atlas. Relative values of these cytoarchitectonic parameters were calculated and averaged over the seven cortical lobes (frontal, parietal, temporal, occipital, hippocampal, insular and sub-lobar). Analysis of variance (ANOVA) was used to determine differences between on cytoarchitectonic properties across the lobes

Results Our results show that the cortex is thickest in the anterior temporal lobe. Thinnest regions were observed in the medial occipital lobe and in the postcentral region of the parietal lobe. A high density of neurons was found in the primary visual cortex, while layer V contained a relatively higher size of neurons in most lobes of the cortex

Conclusions

The cytoarchitectonic properties of the cerebral cortex showed significant differences across lobes. These differences depend on the respective lobes, structural arrangement and their functions.
