AB  - Plethodontid terrestrial salamanders are emerging models in the study of the 
      evolution of chemical communication in vertebrates. Their vomeronasal system is 
      well defined. It comprises sensory neurons in the epithelium of the vomeronasal 
      organ, whose axons form the vomeronasal nerve projecting to the accessory 
      olfactory bulb (AOB), which in turn projects to the vomeronasal amygdala through 
      the accessory olfactory tract. A detailed description of the cellular elements of 
      the urodele AOB is lacking. Neuronal morphology in the AOB was studied by means 
      of biocytin intracellular injections and retrograde tract tracing in the 
      salamander Plethodon shermani. The AOB exhibits the characteristic lamination of 
      olfactory bulbs, except that it displays a mixed periglomerular and mitral somata 
      layer superficially. Mitral cells are the only AOB neurons projecting to the 
      vomeronasal amygdala. Each mitral cell sends multiple axonal branches, generally 
      through both dorsal and ventral portions of the accessory olfactory tract. Some 
      mitral cells additionally send axon collaterals in the white matter immediately 
      ventral to the AOB. AOB interneurons are divided into superficial periglomerular 
      and deep granule cells, each category exhibiting morphological variety. Some 
      neurons in the granule cell layer of the AOB or the region ventral to the AOB 
      have dendritic trees that cover both regions. The present study is the first to 
      highlight the full anatomical extent of single AOB neurons and surprisingly 
      suggests that the ventrolateral telencephalon found below the AOB is part of the 
      salamander vomeronasal system.
