TI  - Connections of the corticomedial amygdala in the golden hamster. I. Efferents of 
      the "vomeronasal amygdala".
PG  - 81-98
AB  - The medial (M) an posteromedial cortical (C3) amygdaloid nuclei and the nucleus 
      of the accessory olfactory tract (NAOT) are designated the "vomeronasal amygdala" 
      because they are the only components of the amygdala to receive a direct 
      projection from the accessory olfactory bulb (AOB). The efferents of M and C3 
      were traced after injections of 3H-proline into the amygdala in male golden 
      hamsters. Frozen sections of the brains were processed for autoradiography. The 
      efferents of the "vomeronasal amygdala" are largely to areas which are primary 
      and secondary terminal areas along the vomeronasal pathway, although the 
      efferents from C3 and M terminate in different layers in these areas than do the 
      projections from the vomeronasal nerve or the AOB. Specifically, C3 projects 
      ipsilaterally to the internal granule cell layer of the AOB, the cellular layer 
      of NAOT, and layer Ib of M. Additional fibers from C3 terminate in a 
      retrocommissural component of the bed nucleus of the strain terminalis (BNST) 
      bilaterally, and in the cellular layers of the contralateral C3. The medial 
      nucleus projects to the cellular layer of the ipsilateral NAOT, layer Ib of C3, 
      and bilaterally to the medial component of BNST. Projections from M to 
      non-vomeronasal areas terminate in the medial preoptic area-anterior hypothalamic 
      junction, ventromedial nucleus of the hypothalamus, ventral premammillary nucleus 
      and possibly in the ventral subiculum. These results demonstrate reciprocal 
      connections between primary and secondary vomeronasal areas between the secondary 
      areas themselves. They suggest that M, but not C3, projects to areas outside this 
      vomeronasal network. The medial amygdaloid nucleus is therefore an important link 
      between the vomeronasal organ and areas of the brain not receiving direct 
      vomeronasal input.
