Our project, started in October 2016, aims to build the adult olfactory connectome of Drosophila. That is, to describe every neuron that is involved in olfactory behaviour, and its connections. We are part of a consortium of groups in Cambridge (Jefferis, Landgraf), Oxford (Waddell) and Janelia Research Campus (Rubin, Bock labs) that are doing this, using a whole brain EM volume generated at Janelia by Davi Bock's group.
The project focuses on the pathways and neuropils involved in innate and learned olfactory behaviour, from the primary olfactory centre - the antennal lobe - to the integration centres - lateral horn (LH) for innate and mushroom body (MB) for learned behaviours. Within the MB, we wish to describe the modulation of dopaminergic neurons (convey valence), onto the Kenyon cells-MB output neurons synapses, the site of likely synaptic plasticity. For the LH, we wish to understand if there is integration of odours of similar valence, and how this integration is achieved.
Computational techniques: electron microscopy reconstruction, image registration, image analysis
