TI  - Social environment affects synaptic structure in the glomerulus of the accessory 
      olfactory bulb of the hamster.
PG  - 187-93
AB  - The accessory olfactory bulb (AOB) is the primary center of the vomeronasal 
      chemosensory system. The effects of differential rearing on the numerical density 
      and size of synapse as well as neuronal size were examined in the AOB of adult 
      hamster. At 30 days from birth, male littermates were assigned to one of three 
      experimental conditions. (1) the IC (isolated condition), where a male animal was 
      housed alone, (2) the NC (neighbor condition), where one male was separated from 
      two females by wire shields, and (3) the SC (social condition), where two males 
      and two females were housed together. After 2 months of differential rearing, the 
      AOBs of male littermates from each experimental set were prepared for 
      morphological examination. The lengths of synaptic contact zones and the density 
      of synapses in the glomeruli of the AOB as well as the area of somata of 
      mitral/tufted cells were measured with an image analyzer. The synaptic contact 
      zone was longer in the SC compared with both the IC and the NC while there was no 
      difference in the synaptic density among the three groups. The somal area of 
      mitral/tufted cells was larger in both the SC and the NC compared with the IC. 
      These results indicate that the exposure to different rearing conditions induces 
      differential morphological changes in both synapses and somata in the AOB of 
      adult hamster.
