  • The laminar distribution pattern of CB1-positive somata and the two main colocalizing markers (CCK and CaBP) are shown. The first row indicates the relative number of CB1-positive cells in the different cortical layers; the second and the third rows show the ratio of the colocalization (number of cells, number of colocalizing cells, and the percentage of the colocalization) with CCK and CaBP, respectively. The columns contain the data from the different layers.
