AB  - The neuronal organization of the accessory olfactory bulb (AOB), which receives 
      sensory information from the vomeronasal organ, was described in a squamate 
      reptile (Podarcis hispanica) by means of light microscopy. Using the 
      Golgi-impregnation method, seven neuronal types could be distinguished: 
      Periglomerular cells constitute a morphologically heterogeneous population of 
      small neurons located between and around the glomeruli. The mitral cells are 
      diffusely distributed in the AOB. Their cell bodies are usually located within 
      the mitral cell layer, but some of them could be also observed in the plexiform 
      layers. Mitral cells were classified into three subgroups on the basis of their 
      sizes and dendritic tree morphologies. Thus, the "outer mitral cells" have the 
      biggest cell bodies, and their distal secondary dendrites are mainly distributed 
      rostrocaudally in the external plexiform layer. The "inner mitral cells" have 
      large cell bodies, and their secondary dendrites are distributed dorsoventrally 
      and are located deeper than those of the other two subgroups. The third type, the 
      "small mitral cells," is the smallest one among mitral cells in the AOB, and from 
      their cell bodies, only two main dendritic trunks arise. The granule cells are 
      composed of several categories based on their different cell body locations and 
      dendritic tree morphologies. Thus, the "superficial granule cells" are located 
      exclusively in the external plexiform layer and have small dendritic fields. The 
      "middle granule cells" have fusiform cell bodies-situated in the internal 
      plexiform layer-and present a wide dendritic projection area. Finally, the "deep 
      granule cells" are distributed throughout the granule cell layer and include a 
      great variety of dendritic tree morphologies. The distribution and morphological 
      features of all neuronal types constituting the AOB of Podarcis were compared 
      with those reported on other vertebrates. The results suggest that the lamination 
      pattern and neuronal organization of the AOB in lizards are more similar to that 
      of mammals than to that of the remaining vertebrates.
