“…Visual input to the collar has been convincingly demonstrated only in honey bees [Mobbs, 1982;Gronenberg, 1986]. Vowles [1955;1964] and Goll [1967] found basically the same visual tracts in the honey bee and in the ant Formica rufa but, similar to previous authors, they were not able to demonstrate an actual connection between the collar and the optic lobes. Such a connection has now been established for ants of different subfamilies.…”

“…In all insects studied [Burrows et al, 1982;Homberg et al, 1988;Malun et al, 1993], including the honey bee [Mobbs, 1982;Homberg, 1984] and ants [Formica; Jawlowski, 1959;Vowles, 1955;Goll, 1967], neuropil homologous to the lip region receives input that originates from the antennal glomeruli. Visual input to the collar has been convincingly demonstrated only in honey bees [Mobbs, 1982;Gronenberg, 1986].…”

The mushroom bodies are central brain neuropils involved in the control of complex behavior. In ants, the mushroom bodies are relatively large compared to those of honey bees, whereas the optic lobes of ants are considerably smaller. The general morphology of ant mushroom bodies is similar to that of honey bees. As in other Hymenoptera, the main input region of the mushroom bodies, the calyx, is subdivided into three compartments: the lip, the collar, and the basal ring. In many ant species this compartmentalization is not obvious and can only be visualized using neuronal tracers. The lip region receives antennal input and is large in all ant species. It appears to be composed of at least two different regions that have not yet been characterized in detail. The collar is large in other Hymenoptera, yet in ant workers it varies in size and is always much smaller than the lip region. The collar receives visual input and is relatively larger in males, which generally are more dependant on vision than are workers. The basal ring receives input from both the optic and antennal lobes. In one ant tribe, the Ponerini, the collar region appears to have changed its position, but based on afferent input it appears to be homologous to the hymenopteran collar. Generally, the composition of the mushroom body calyx correlates with the living conditions of ants, reflecting the great importance of olfaction and the lesser and more variable significance of vision for workers of the observed ant species.

Brain morphology, with special attention to the three dimensional form of the corpora pedunculata, was studied in thirteen species of ants, representing four subfamilies of Formicidae. The results can be summarized as follows. (1) The neural systems processing optic and olfactory information differ in the evolutionary history among the studied taxa. A positive correlation can be demonstrated in the phylogenetic history of the corpora pedunculata, central body, cerebral bridge and olfactory lobe, but not the optic lobe. Ant species with very large eyes and thus, probably, highly developed vision, show gigantic optic lobes, with no exaggeration of any other brain structure. (2) More social species have more complex chemical communication systems and better developed corpora pedunculata (more surface in foldings of the calyces) and olfactory lobes; however, this tendency seems to reverse in highly social species with a sophisticated polymorphic caste system: individuals of these species are generally less developed neurally. (3) There are differences between the form of the internal and external calyces of the corpora pedunculata, and these differences are proportionately more pronounced in species with complex social organization. (4) Individuals from different worker castes of the same species differ in their brain morphology, but each species shows a different pattern of variation among their castes. (5) Brain structure shows characteristic marks due to the different phylogenetic developments in the taxa studied. For example the trends in brain volume-body size ratio are different for the various subfamilies, suggesting a divergent phylogenetic history.

“…They are involved essentially in learning behavior and memory formation in insects (Apis: Menzel et al, 1974;Erber et al, 1980Erber et al, , 1987Hammer and Menzel, 1995;Drosophila: Heisenberg et al, 1985;De Belle and Heisenberg, 1994;Connolly et al, 1996). Since their discovery (Dujardin, 1850), their anatomical organization, their connectivity within the insect protocerebrum, and their behavioral development have been described (Kenyon, 1896;Vowles, 1955;Goll, 1967;Steiger, 1967;Pearson, 1971;Schü rmann, 1974;Strausfeld, 1976;Weiss, 1981;Mobbs, 1982Mobbs, , 1984Rybak and Menzel, 1993;Withers et al, 1993;Fahrbach et al, 1995; for review, see Mobbs, 1985;Schü rmann, 1987;Menzel et al, 1994). Detailed neuroanatomical studies of individual MB neurons or groups of neurons, however, are rare.…”
