>"Synaptic circuits in the Drosophila nervous 
>system: the prospect of a wiring diagram for the fly's brain"
>Summary
>A major task in neuroscience, to relate the 
>brain's circuits to external behaviour, has so 
>far been largely frustrated by the anatomical 
>complexity of the former and the fluidity of the 
>latter.  Recent technical advances have begun to 
>provide access to both problems, at least in 
>some species.  The fruit fly Drosophila 
>melanogaster offers genetic tools to label 
>neurons and to perturb their function in 
>identified circuits, and the dimensions of its 
>brain allow neurons to be imaged in wholemounts, 
>and its synaptic circuits to be reconstructed 
>from serial-section electron microscopy 
>(ssEM).  The visual system in Drosophila is well 
>suited to this task, because its component 
>neurons are morphologically determinate and its 
>synaptic circuits are repeated as an array of 
>parallel columns.  Hitherto, the analysis of 
>circuits has been blocked at the second 
>neuropile, the medulla.  I will present recent 
>our mostly ssEM findings on this, the largest 
>neuropile of the fly's brain, that begin to open 
>up the visual system to functional 
>analysis.  These herald, we hope, the 
>possibility for parallel approaches on other 
>brain regions that will in the end help generate 
>the connectome of the fly's brain.
