    Notes: Summary The cerebral cortex of the albino mouse was examined by means of a quantitative method. An image analyzer was used in conjunction with an automatic scanning procedure to determine the grey level index in Nissl-stained sections. Computer plots of various ranges of grey level indices enabled delineation of cortical areas, from which cortical maps were graphically reconstructed. The cortical areal pattern is, in some regions, similar to the commonly used map of Caviness (1975) but differes considerably in other regions, especially in the temporal one. Furthermore, the primary visual cortex of the mouse was shown to be composed of two distinct cytoarchitectonic areas. The results of the study are discussed with respect to the literature on anatomical and functional localizations in the mouse cerebral cortex.

    Notes: Summary The cerebral cortex of the guinea pig has been examined by means of a quantitative cytoarchitectonic method (Schleicher et al. 1978; Zilles et al. 1978a). In this method, a computer-controlled automatic image analyzer determines the grey level index of microscopic fields measuring 50x50 μm in Nissl-stained sections by a systematic scanning procedure. Computer plots of serially sectioned histological slides from three hemispheres were produced by printing selected ranges of grey level indices. The delineation of cortical areas was worked out in these plots based on quantitative criteria. Cortical maps of the areal pattern were reconstructed graphically. The resulting cortical map of the guinea pig differes from that of Rose (1912), but it corresponds to the results of Friede (1960) and is in agreement with neurophysiological studies. In general, the areal pattern of the guinea pig is similar to that of the rat (Zilles et al. 1980), but there are also some differences. These differences are discussed with respect to functional considerations.
