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

181 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.
