Chapter 2 The synaptic populations of the fly's optic neuropil and their dynamic regulation: Parallels with the vertebrate retina

The effects of 20-hydroxyecdysone on the differentiationin vitro of cells from the eye imaginal disc fromDrosophila melanogaster

“…The second is that the early assembly of presynaptic components in vitro occurs in the absence of the photoreceptor's normal target cells in the optic lobe. This corresponds with observations in vivo that presynaptic organelles can form either in the absence of target cells or opposite glial cells (Meinertzhagen, 1993).…”

Gene expression patterns in primary neuronal clusters of the Drosophila embryonic brain

“…The brain of Drosophila is formed by structurally complex compartments, including (among many others) the mushroom body (Strausfeld et al, 1998;Jefferis et al, 2002), the central complex (Strauss and Heisenberg, 1993;Renn et al, 1999), the optic ganglia (Meinertzhagen, 1993;Morante and Desplan, 2004) and the olfactory glomeruli of the antennal lobe (Stocker, 1994;Laissue et al, 1999). The neurons of the mushroom body and some of the antennal lobe projection neurons have been traced back to embryonic brain elements (Lee et al, 1999;Noveen et al, 2000;Kurusu et al, 2002;Marin et al, 2005;Ramaekers et al, 2005).…”

Adaptation of microglomerular complexes in the honeybee mushroom body lip to manipulations of behavioral maturation and sensory experience

“…If similar conditions would apply to the system studied here we have to postulate that the larger volume of boutons leads to more efficient synaptic transmission probably because of the larger presynaptic (and possibly also postsynaptic) compartments. On the other side, if the relationship between pre-and postsynaptic membrane area is kept constant, as it appears to be the case in the first neuropil in flies (Meinertzhagen, 1993) the larger bouton volume would reflect a larger number of presynaptic sites on the grown area of the PN boutons. The observed changes in the number and density of microglomerular complex might also induce a remodeling process (Stepanyants et al, 2002) at their postsynaptic sites, the formation or elimination of KC dendritic spines (postsynaptic sites) or changes in the arborization pattern of KCs and inhibitory feedback neurons from the MB lobes, both of which receive input and serve as presynaptic sites to the PN bouton (Ganeshina and Menzel, 2001).…”
