AB  - A total of 134 individuals from 75 species were investigated with regard to 
      existence and size of the accessory olfactory bulb (AOB). Based on volume 
      measurements the AOB and its three measured components do not show any uniform 
      trend in size changes from lower Insectivora through higher Primates. The 
      investigated structures are in most prosimians clearly larger than in low 
      Insectivora, in most New World simians clearly smaller, and in Old World simians 
      absent. Even within narrowly related groups there may exist strong differences in 
      size and structural differentiation. In AOBs of large relative size, the inner 
      granular layer (layer 6) is relatively larger than in AOBs of small relative 
      size. The variability in size is especially large in those individuals and 
      species with a relatively small AOB. No differences were found between the AOBs 
      (1) of the two sides within the same individual (brain) and (2) between the two 
      sexes within the same species. There is no interdependency in size between MOB 
      (main olfactory bulb) and AOB. The relative size of the AOB is discussed in 
      relation to various ecological and behavioural considerations. No clear relations 
      could be found between the size of the AOB and dietary specialization. A 
      comparison of the relative size of the AOB with activity cycle, sexual behaviour 
      and the use of pheromones in various species of Primates supports the suggestion 
      that the vomeronasal system may be involved in sexual and/or social interaction.
