The project aims to generate the first synaptic-resolution connectome for a whole male adult Drosophila melanogaster central nervous system, from an electron microscopy volume obtained at HHMI Janelia Research Campus in the US. The goal is to obtain a comprehensive understanding of some of the sensory, motor and sensory-motor integration circuits, as well sexually dimorphic differences.

The project is a collaboration with co-applicants at Janelia, the MRC LMB in Cambridge and the University of Oxford Centre for Neural Circuits and Behaviour.

Current research topics include:

  • To reconstruct the neurons that connect the brain and the ventral nerve cord and identify their role in the flow of information and sensory-motor integration.
  • To comprehensively identify and describe the intrinsic neurons of the ventral nerve cord.
  • To better understand morphological and connectivity variability, within and between individuals, including sexually dimorphic differences
  • To develop robust workflows and open source software that allows the analysis of large neuroanatomical datasets.
