Comparison of laminar receptor densities of kainate receptor in IPL areas. A: Coronal sections through four caudo-rostral levels of a macaque hemisphere showing kainate receptor distribution patterns in the IPL. The borders between the IPL areas (red lines) are charted on the pseudocolor-coded autoradiographs. The color bar beneath each autoradiograph indicates receptor concentrations by the different colors, from dark blue for low to red for high concentrations (fmol/mg protein). B: Laminar distribution pattern of representative fields of IPL areas. Roman numerals indicate cytoarchitectonic layers. C: Bar plot shows receptor densities in each layer for the IPL areas, separately. Receptor densities (y axis) are given in fmol/mg protein. Brackets across bars denote the areas which have significant inter-area differences in laminar densities (* p < 0.05, ** p < 0.01).
