FIGURE 4.
Correlations between numbers of spontaneous epileptic seizures and immunolabeling for somatostatin (SOM) and calretinin (CR) in the subiculum. (A, B) The intensity of SOM labeling in the outer molecular layer of the subiculum was positively correlated with numbers of spontaneous seizures experienced for 3 months (A), but the intensity of CR labeling was negatively correlated with seizure numbers (B). (C) Labeling intensities of SOM- and CR-immunoreactivity revealed a strong inverse correlation in this layer (Pearson correlation coefficient).
