The development of the sulci and gyri of the bovine cerebral hemispheres.

Louw GJ.AbstractThis study contributes to the existing knowledge and includes a complete description of the gyri and sulci of the bovine cerebral hemisphere, the chronological order of appearance of these sulci and gyri and the ages at which the sulci and gyri reach their final pattern as seen in the bovine adult. The research was undertaken because this specific area has not been covered by anatomists in any depth. The results of this study will contribute to the more complete descriptions of the anatomy of the bovine adult, as well as of the embryological development of the animal. A number of bovine embryos and fetuses were collected from the abattoir. Serial sections of the embryos were studied histologically, while the brains of the fetuses were examined macroscopically or with a dissection-microscope. Up until day 58 the cerebral hemisphere is smooth. Then an indentation appears which marks the position of the Fissura sylvia. The Sulcus rhinalis lateralis appears at day 68. At day 90 the following grooves are visible: the Sulcus suprasylvius, the Sulcus cinguli, the Sulcus splenialis, the Sulcus genualis, and the Sulcus corporis callosi. At this age, all the gyri associated with these sulci develop, although the gyri are well developed only after the grooves have formed. At day 110 the Sulcus ectosylvius, the Sulcus marginalis, and the Sulcus presylvius are visible, once again with their associated gyri appearing a short time thereafter. At day 130 the following grooves are visible: the Sulcus coronalis, the Sulcus cruciatus, the Sulcus ansatus, and the Sulcus endomarginalis. The cerebrum of the foetus at this stage has well developed gyri. At day 160 the Sulcus proreus, the Sulcus ectomarginalis, the Sulcus suprasplenialis, the Sulcus endosplenialis, the Sulcus calcarinus, and the Sulcus endogenualis have developed. The final groove to form is the Sulcus rhinalis medialis. Then the brain looks like that of the adult animal.

Quantitative analysis of the laminae of the striate area in man. An application of automatic image analysis.

Sauer B.Abstract181 cortical fields from the striate area of 11 normal, adult brains were studied using the grey level index method. The absolute and relative thickness, the relative portion of the GLI profile, and the mean absolute and relative GLI of the different laminae of the striate area were measured. The values for the laminae were analysed for correlation. Significant correlations could partly be explained by the influence of the geometrical shape of the cortex. The lamina data of one brain were examined in relation to the position in the sulcus calcarinus.
