“…In accordance with our findings, it was known from previous studies in vertebrates as well as in invertebrates that light-dependent neuronal activity shapes neuronal circuits in the visual system (reviews: Hirsch et al, 1995;Heisenberg et al, 1995; Aamodt and -Paton, 1999). In D. melanogaster, changes in light levels changed the volume of light-dependent neuropils in the brain .…”

Pigment-dispersing factor-immunoreactive neurons anterior to the accessory medulla (aPDFMes) in the optic lobes of insects are circadian pacemaker neurons in cockroaches and fruit flies. The authors examined whether any of the aPDFMes of the cockroach Leucophaea maderae are sensitive to changes in period and photoperiod of light/dark (LD) cycles as a prerequisite to adapt to changes in external rhythms. Cockroaches were raised in LD cycles of 11:11, 13:13, 12:12, 6:18, or 18:6 h, and the brains of the adults were examined with immunocytochemistry employing antisera against PDF and orcokinin. Indeed, in 11:11 LD cycles, only the number of medium-sized aPDFMes specifically decreased, while it increased in 13:13. In addition, 18:6 LD cycles increased the number of large- and medium-sized aPDFMes, as well as the posterior pPDFMes, while 6:18 LD cycles only decreased the number of medium-sized aPDFMes. Furthermore, PDF-immunoreactive fibers in the anterior optic commissure and orcokinin-immunoreactive fibers in both the anterior and posterior optic commissures were affected by different lengths of light cycles. Thus, apparently different groups of the PDFMes, most of all the medium-sized aPDFMes, which colocalize orcokinin, respond to changes in period and photoperiod and could possibly allow for the adjustment to different photoperiods.

“…we conclude that in Drosophila melanogaster some aspects of visual orientation behavior as assessed in the flight simulator are not fully matured until four days after eclosion from the pupa. Behavioral maturation at this late age also has been reported recently by Hirsch et al (1990Hirsch et al ( , 1995Barth et al 1996), who observed that dark rearing affects the flies' behavior in a visual orientation task and in a courtship competition assay and that these differences are apparent after 4 but not yet after 2 days of dark rearing. Learning indices in conditioned visual orientation in the flight simulator are affected by a large number of behavioral parameters and may not directly reflect synaptic plasticity.…”

“…Moreover, for several years data are now accumulating that demonstrate massive behavioral consequences of the very rearing conditions that cause the structural changes (Hirsch et al 1990). For instance, flies kept for 4 days in one of several light regimes (LL, DD, LD) prefer mates that were raised under the same conditions (Barth et al 1997a; see also Hirsch and Tompkins 1994;Hirsch et al 1995). A similar mate preference has been observed for flies that were either raised solitary or in groups of 50 animals (Ellis and Kessler 1975;see Heisenberg et al 1995 for the corresponding structural effects in the brain).…”

The brain of Drosophila is structurally altered by sensory stimuli that the flies receive during their adult life. Size and fiber number of the mushroom bodies, central complex, and optic lobes are influenced by social, spatial, or olfactory cues. Recently, the optic lobes have been shown to depend on the light regime that flies experience. Structural plasticity in the brain is thought to be a correlate of functional adaptations and long-term memory. We therefore extend our investigation of volume changes to the calyces of the mushroom bodies and the central complex. We show that rearing flies in constant light for 4 days increases the volume of both structures by up to 15% compared to rearing them in total darkness. Much of this difference develops during the first day. The effect of light is not hormonally mediated, as monocularly deprived flies develop a smaller ipsilateral calyx. Mutant analysis suggests that light generates its effects through known visual pathways. In contrast to the optic lobes, in the calyx and central complex structural changes can be linked to cAMP signaling, as in the mutants dunce z and amnesiac 1 no volume differences are observed. Surprisingly, the mutant rutabaga ~ shows a prominent light-dependent volume increase in the calyx and central complex, dissociating structural from behavioral plasticity. In complete darkness wild-type flies grow larger calyces under crowded conditions in their normal culture vials than if kept in small groups on fresh food. This stimulating effect of crowding is not 1Corresponding author. observed in any of the cAMP mutants, including rutabaga 1.
