TI  - A horseradish peroxidase study of the olfactory system of the frog, Rana 
      esculenta.
PG  - 400-17
AB  - The olfactory system of the frog Rana esculenta was studied by using horseradish 
      peroxidase (HRP) tracing of axonal pathways. Injections of HRP were made in the 
      main olfactory bulb (MOB), accessory olfactory bulb (AOB), anterior olfactory 
      nucleus (AON), the amygdala (AMY), and in a zone of the leteral wall of the 
      telencephalic hemisphere immediately posterior to the AOB. Projections from these 
      sites are described and are generally similar to those obtained by degeneration 
      methods. However, HRP reveals more extensive olfactory connections than 
      previously reported. Ipsilateral, contralateral, and bilateral projections are 
      described. The MOB, AOB, and AON have ipsilateral connections to each other. The 
      MOB and AOB have very different projections. The MOB and AON project via the 
      habenular commissure (HC) to the contralateral medial wall of the telencephalon. 
      Ipsilateral MOB fibers also terminate in this cell-free zone where the medial 
      forebrain bundle (MFB) originates. The AOB projects to the lateral cortex of the 
      contralateral telencephalic hemisphere via the HC and also to the ipsilateral AMY 
      and lateral forebrain bundle (LFB) from where some fibers project 
      contralaterally. HRP injections in the AMY retrogradely fill cells in the 
      ipsilateral AOB, two nuclei of the ipsilateral hypothalamus and a nucleus of 
      cells caudal to the ipsilateral nucleus isthmi. Fibers are also labeled that 
      project to the contralateral AMY. Few fibers were observed to decussate in the 
      interpeduncular nucleus or optic chiasma. No olfactory fibers were found to 
      project to the habenular nuclei, and no labeled neurons were found to project to 
      the olfactory bulbs. No morphological asymmetry was observed qualitatively in the 
      distribution of olfactory fibers in the two halves of the brain.
