Analysis of the hippocampal CB1R-immunopositive area. In the CA1 region (a) the CB1R-immunopositive area was decreased in idiopathic epilepsy in comparison to structural epilepsy and controls. In DG (b), CA3 (c) and hilus (d) the area expressing CB1R in idiopathic epilepsy was significantly smaller in comparison to structural epilepsy, but did not differ significantly to controls; error bars indicate SEM and asterisks in the figures indicate significant differences, *p < 0.05, **p < 0.01, ***p < 0.001; CA: Cornu Ammonis; DG: dentate gyrus.
